Niš Constantine the Great Airport (INI) Airport Guide 2026 — Free Buses, Cheap Taxis, Real Dinars

Last verified: September 2026.

🏢 1. One Terminal, an Access-Control Desk, and Passport Booths on Both Sides

Niš is a single-terminal airport operated by Aerodromi Srbije d.o.o., the Serbian state airports company, at Ulica vazduhoplovaca 24. Check the address you are typing into a booking site, because the airport’s old domain has moved: nis-airport.com now redirects permanently to ini.aerodromisrbije.rs. The email address on the airport’s own contact block still ends in @nis-airport.com, so both are live — but the website you want is the second one.

The traffic story here is genuinely good news, and the airport’s own statistics page hides it. That page publishes an annual series that stops at 2024 and reads badly: 357,313 passengers in 2024, down 20% on 2023’s 448,312, with aircraft movements down 12%. Take that at face value and Niš looks like an airport in retreat. It is not. The airport’s own news reports growth in every month it published through 2026: 37,814 passengers in May 2026, up 14% year on year on 304 operations, and then 52,803 passengers in August 2026, up 12% year on year, on 548 flights — which the airport calls a new record for the number of air operations in a month, alongside 592,580 kg of cargo. The published annual table has simply not been brought forward. Judge this airport by the monthly numbers, not the annual page.

The building is small, and the passenger flow has three distinct checks in it. First comes access control, a counter where you show your boarding pass and a valid identity document, and where staff check the number, dimensions and weight of your hand baggage before sending you to screening. That is a real check, not a formality — bring your cabin bag inside your airline’s limits rather than hoping. Parents with babies under two and passengers travelling with airport assistance get priority in this queue. Compare your carrier’s allowance on our baggage checker before you go; if you are on one of the low-cost carriers here, the Ryanair baggage allowance guide and the Wizz Air baggage allowance guide carry the current numbers.

Second is security screening, which sits immediately before passport control. The airport asks you to take metal objects out of your pockets — phone, keys, coins — and to remove liquids, gels and aerosols and electronic devices such as laptops and cameras from your cabin bag into a tray, along with your jacket or coat, and sometimes your shoes. The liquids rule is the standard one: containers of no more than 100 ml, up to 1,000 ml in total per passenger, in transparent plastic bags. A nice detail the airport publishes and most do not: you can ask airport staff for a transparent bag rather than losing your toiletries because you forgot one. If you have a metal implant, tell the screening staff and carry the medical documentation — screening is then done in a separate cabin. If you have a pacemaker or any other health reason, say so before screening starts, not during it.

Third is passport control, and it exists in both directions. Departing passengers pass it immediately after security; arriving passengers meet it immediately on entering the terminal building. This is not a formality either — see the next section on why the entry stamp matters more here than at most airports.

The airport is not new, whatever the terminal looks like. Its own history records the first flight from Niš on 1 May 1935, when Aeroput flew Belgrade–Niš–Skopje–Bitola–Thessaloniki; a concrete runway at the present site in 1952; and the passenger terminal built between 1985 and 1986. It reopened formally for air traffic on 12 October 1986, with a JAT Boeing 737-300 landing in front of tens of thousands of spectators.

🛂 2. Serbia Is Outside the EU — Its Own Rules, and the 24-Hour Registration

Serbia is not a member of the European Union and does not use the euro. Arriving here is a full international border crossing with a stamp, and the rules are Serbia’s own. Three things matter, and one of them catches almost every independent traveller.

First, your passport. The Serbian Ministry of Foreign Affairs sets a specific standard: a valid passport, valid for at least 90 days after your intended date of departure from Serbia, with at least two consecutive blank pages, and issued within the past 10 years. Read all three conditions. The blank-pages requirement and the ten-year issue rule are the ones people fail, and a passport renewed with extra months carried over from an old one can breach the second.

Second, whether you need a visa. Serbia operates its own visa regime, country by country, and you should check your own nationality on the Ministry’s visa-regime page before booking. British citizens can visit visa-free for up to 90 days in any six-month period for tourism or business, on GOV.UK’s current guidance. Separately, and usefully, a Government decision of 30 October 2014 allows holders of any national passport who hold a valid Schengen, UK, EU member state or United States visa — or a residence permit in one of those areas — to enter, transit and stay in Serbia for up to 90 days in a six-month period without applying for a Serbian visa, within the validity of that visa or permit. If you need a Serbian visa, note that since 23 April 2025 Serbia has issued Digital Travel Authorizations in electronic form for nationalities where the service is enabled, applied for through the government’s foreigners’ portal — otherwise you get a conventional sticker visa in the passport.

Third — and this is the one Peter’s question was right to flag — you must register your stay within 24 hours. It is still in force. GOV.UK states it plainly: “You must register with the local police where you’re staying within 24 hours of your arrival in Serbia.” The Serbian Foreign Ministry describes the obligation from the other side: legal entities and individuals providing paid accommodation, people being visited by a foreign national, and the foreign national themselves must register within 24 hours from the provision of accommodation, or from the time of arrival for a visit.

In practice this splits cleanly into two cases.
– Staying in a hotel, hostel or a registered apartment? Reception does it for you at check-in and you never see the paperwork. This is why most visitors have never heard of the rule.
– Staying with friends, family, or in unregistered private accommodation? Nobody does it for you. You and your host are jointly responsible, and you have 24 hours. The consequence GOV.UK publishes is not trivial: “If you do not register, you could get a fine, and face arrest and a court appearance.” The slip travellers still call the “white card” is what you get back — keep every one until you leave.

And a fourth thing, which is peculiar to Serbia and worth a full paragraph. Make absolutely certain your passport is stamped on entry. GOV.UK’s warning is unusually severe: “If you try to leave Serbia without an entry stamp you could face charges of illegal immigration, a heavy fine and a prison sentence.” If you arrive at a quiet moment and the officer waves you through, ask for the stamp. Check the page before you walk away from the booth. This costs you ten seconds and it is the single highest-consequence thing in this guide.

Money, and the honest answer: get dinars. Serbia’s currency is the dinar (RSD), and every price you will meet at this airport is published in it — the taxi tariff, the parking tariff, the airport’s own schedule of charges. The National Bank of Serbia’s official middle rate on 7 September 2026 was €1 = 117.3620 dinars, which makes the mental arithmetic easy: divide by 117 for euros, or knock off two zeros and take a bit off. Do not plan on paying for a taxi or a bus in euros. Change money at a licensed exchange office in the city rather than accepting the first rate you see, use the NBS middle rate as your reference for what is fair, and if a card terminal offers to bill you in euros, decline — that is dynamic currency conversion and the margin is not yours.

🚌 3. Lines 34A and 34B, and the Reason They Cost Nothing

This is the cheapest airport transfer in Europe, because it is free. Niš runs the airport bus as part of its ordinary city network, and since 1 July 2025 public transport in Niš has been free for all passengers. No ticket, no tap, no machine, no queue at a kiosk. Walk out of the terminal and get on.

The service is a circular route with two directions, and picking the right one matters.

Neither the airport nor the city publishes a door-to-door journey time for the airport run, so we are not going to print one. What the airport does publish is the taxi comparison, and it tells you the distance is small: a taxi to the city centre is quoted at roughly 250 dinars, which is a short ride at Serbian rates.

Taxis are cheap and the airport publishes actual numbers, which is rare enough to be worth quoting exactly. The rank sits 50 metres from the passenger terminal exit, next to the car park. Every registered taxi company starts at 150 dinars — about €1.28 — and, in the airport’s own words, “depending on your destination, the ride may cost anywhere from 250 dinars (to the city center) to 1000 dinars (to Niška Banja).” That is roughly €2.13 into town and €8.50 out to the spa suburb. Use registered cars from the rank, and if the meter is not running, ask.

Parking is straightforward and the price list has been in force since 1 February 2024:

The car park is guarded, under constant video surveillance and open 24 hours. ⚠️ Keep the ticket you take at the barrier. Losing it means paying for a replacement at a much higher rate, with a stated minimum of 1,000 dinars.

Car hire is available at the airport through rent-a-car agencies listed on the airport’s own site, and it is the sensible option if southern Serbia rather than Niš itself is the point of the trip — Devil’s Town and the villages of the Nišava valley are not bus destinations.

One thing Niš does have that most airports of its size do not: it is a railway city. Line 34A puts you at the main railway station as well as the bus station, so onward travel by train or coach across Serbia starts from a bus you did not pay for.

🛋️ 4. There Is No Lounge, and the Airport Does Not Pretend There Is

Niš has no passenger lounge. We checked it two ways. The airport’s own site has an “At the airport” section whose entire contents are car hire — no lounge, no lounge booking, nothing. And Priority Pass’s Serbia listing contains exactly one airport: Belgrade Nikola Tesla. Niš does not appear. If a third-party site offers to sell you Niš airport lounge access, it is selling you something that does not exist.

What that means in practice is a planning decision rather than a disappointment. Once you are through access control, security and passport control, you are in a waiting area with the gates and not much else. Do your eating, your coffee and your working before you go airside, and do not arrive four hours early expecting somewhere comfortable to sit it out. On a small airport with a handful of daily rotations, the honest arrival window is the one your airline specifies, plus a margin for the hand-baggage check at access control — which, unlike at bigger airports, is a real gate rather than a wave-through.

The compensating advantage is speed. Fifty-two thousand passengers in August 2026, its heaviest month on record for flights, works out at under 1,800 a day across every departure and arrival. At that throughput there is no scope for the queues a hub generates, and there is no walk between distant piers. What you lose in comfort you get back in time.

🍽️ 5. Money, Food, and What Southern Serbia Puts on a Plate

Terminal catering at Niš is minimal and the airport does not publish an outlet list, so plan to eat in the city rather than at the gate — which, given what Niš eats, is the better outcome anyway.

Southern Serbia is grill country, and Niš is its capital. The regional cooking is built on charcoal-grilled meat — ćevapi, pljeskavica, ražnjići — eaten with raw onion, kajmak (a thick clotted dairy spread that is closer to cheese than cream) and ajvar, the roasted red-pepper relish that southern Serbia is known for and that households still make at home each autumn. The burek is taken seriously enough that the city’s own tourism organisation publishes a guide to where the best one is. Order rakija — the fruit brandy, usually plum — after the meal rather than before, and expect it to be poured generously.

The traditional place to eat is a kafana, the Serbian tavern, and Niš has enough of them that the city tourism board lists kafanas separately from restaurants. That distinction is worth respecting: a kafana is where the grill, the rakija and the live music are; a restaurant is where the menu has pictures.

On money, the practical sequence is this. Arrive with a small amount of euros or your home currency, change enough dinars in the city for a few days at a licensed exchange office, and use cards for anything substantial. The National Bank of Serbia publishes an official middle rate daily — €1 = 117.3620 RSD on 7 September 2026 — and that is the number to sanity-check any offer against. Do not assume euros will be taken. The airport’s own published tariffs are in dinars, the buses are free so you need nothing for them, and the taxi from the terminal wants 250 dinars, not two euros and change.

What to carry home. Serbian food products travel well: ajvar in jars and rakija within your airline’s alcohol limits. Check whether your bag is worth what you are paying for it on our price check tool — on a Wizz or Ryanair fare out of Niš, the hold bag frequently costs more than the seat.

💡 6. What Southern Serbia Is For

Niš is one of the oldest cities in Europe and one of the least visited good ones. Serbia’s national tourism organisation makes the case simply: the Celts named it Naissus, “the nymph’s city”, and its position at the crossroads between East and West made it a favourite stronghold of every power that came through — Celts, Romans, Huns, Avars, Byzantines and Ottomans, all of whom left something standing. It reached its height under Emperor Constantine the Great, who turned it into an administrative and trading centre of the Roman Empire, and after whom this airport is named.

Three sights in the city carry the whole story, and all three are managed by the National Museum of Niš.

Niš Fortress (Niška tvrđava) is the one you cannot miss, because it is in the middle of town. The city’s tourism organisation calls its walls and gates among the finest and best preserved in the central Balkans — 22.1 hectares, with ramparts 8 metres high and 3 metres thick. Fortification on the site starts in the 1st century AD with the Roman legions; Romans, Byzantines and Serbs all built here, it was destroyed and rebuilt repeatedly, and the Ottomans gave it its final form in 1730. The detail that makes it unusual is not the walls but the geography: Niš is one of very few cities anywhere with an imposing fortress in its very centre whose centre of gravity has not moved in two millennia. You walk into it from the main street.

Mediana is the Constantine connection made physical. It is the luxury suburb of ancient Naissus, built at the end of the 3rd and beginning of the 4th century during Constantine’s reign and those of his successors — 40 hectares of archaeological park on Bulevar Cara Konstantina, with the remains of a grand villa with a peristyle, two early Christian churches, a granary, soldiers’ barracks and water towers. More than 1,000 square metres of floor mosaics survive, and they are the reason to go rather than a footnote to it.

Ćele Kula — the Skull Tower — is the hardest thing in this guide to write about, and you should still go. It is exactly what its name says: a tower built of human skulls, and the tourism organisation describes it as a monument unique in the world, visited by over 30,000 people a year. After the Battle of Čegar in 1809, the Ottoman commander of the city, Hurşid Pasha, ordered a tower built from the skulls of the Serbian fighters, set on the road to Constantinople as a warning to the local population. It stands today inside a small chapel on Bulevar Dr Zorana Đinđića. It is not a curiosity and it should not be treated as one.

Outside the city, two things are worth the drive. Niška Banja is the spa suburb — the airport’s own taxi tariff quotes about 1,000 dinars to reach it, so it is close — and it is where the city goes to sit in thermal water. Devil’s Town (Đavolja Varoš) is further, in the heart of Radan Mountain, and it is one of Serbia’s genuinely strange landscapes: the national tourism organisation counts exactly 202 earth figures capped with rock, carved by erosion rather than by anyone. It is a proper day out from Niš by car, and it is not reachable by bus.

Time your visit to a festival if you can. Niš runs Nišville, an internationally known jazz festival, and Nisomnia, both in the summer months, plus the Niš Film Festival every August, which has been running for more than fifty years. A small city with three established festivals is a different place in August from the one you find in February — and August is also when the airport is at full stretch: 52,803 passengers and a record 548 flights in August 2026.

Two practical warnings to close on. First, the schedule here is aggressively seasonal, and the airport publishes the windows: Zurich flew only from 28 June to 23 August 2026, Corfu from 3 June to 30 September, Stockholm from 1 April to 29 August, Tivat from 13 June to 12 September, plus charters to Antalya and Monastir from June to September. The summer programme runs to 24 October. Check that your route exists on your dates before you book anything else — and from 25 October 2026 Air Serbia adds direct Vienna and Malta flights twice weekly, which changes the winter picture materially. Ryanair already serves both cities, and 25 October is the winter-season boundary — neither airline has said whether the Air Serbia flights add to the Ryanair ones or replace them, so check both carriers rather than assuming.

Second, the airport’s own site still links to visitnis.com for tourist information, and that domain no longer resolves. The city’s actual tourism organisation is at visitnis.org, at Nade Tomić 15 in Niš, on +381 18 510 210. Use that one.
