🏢 1. The Terminal & the AirAsia Base

Senai runs from a single main passenger terminal, which keeps things simple: domestic and international departures share the building, and there is no inter-terminal transfer to plan around. A separate business-aviation terminal handles private traffic and does not concern scheduled passengers. The terminal handled roughly 3.4 million passengers in 2024, the bulk of it domestic, and traffic has been climbing — international numbers jumped well over 50% year-on-year — which is the pressure behind the long-running expansion.

The airport is an AirAsia operating base, and that shapes the schedule. Most of what flies in and out is low-cost: AirAsia and its Indonesia and Thailand sister operations across the domestic Malaysian network and to regional Southeast Asian points, with Malaysia Airlines, Batik Air Malaysia and Firefly filling in. There is no long-haul intercontinental network here — Senai is a domestic and short-haul regional airport, and a connection through it is a budget-carrier connection, not a hub transfer.

One practical consequence of a low-cost base: most tickets are sold point-to-point with no through-checked baggage. On a self-connection through Senai you will clear immigration, collect your bag and re-check it for the onward leg, so build the border crossing into any connection time rather than assuming an airside transfer.

The genuine 2026 change is the expansion. Senai is in the middle of an upgrade — a new terminal building, runway and cargo works — aimed at lifting capacity well above the current ceiling toward roughly 10–12 million passengers a year. Completion dates on Malaysian airport projects slip, so treat any specific opening date as provisional and check which terminal your flight uses before you travel rather than assuming a configuration that may not be live yet.

🛂 2. Malaysia’s Border Rules at Senai: Visa-Free Entry & the Digital Arrival Card

What governs arrival here is Malaysia’s national entry system, and nothing else. Two things matter: whether your passport gets visa-free entry, and the digital arrival card almost everyone now has to file.

Visa-free entry — 90 days for many

Malaysia grants visa-free entry to a long list of nationalities. Citizens of the United States, the United Kingdom, EU member states, Australia, Canada, Japan and many others enter without a visa for tourism for up to 90 days. A separate, larger band of countries gets 30 days visa-free, and the visa exemptions were widened in recent years to include Chinese and Indian nationals. Because the per-country allowance (90 vs 30 days, or eVisa) varies, confirm your own passport’s current allowance against the Malaysian Immigration Department before you book rather than assuming the 90-day figure. Travellers who do not qualify for visa-free entry apply for an eVisa online before flying.

The Malaysia Digital Arrival Card (MDAC) — file it before you fly

This is the part that catches people. Malaysia requires most foreign visitors to submit the Malaysia Digital Arrival Card (MDAC) online before arrival, for entry by air, land or sea. The window is narrow: you can file it no earlier than three days (72 hours) before arrival, and you must complete it before you land. It is free on the official Immigration Department portal — ignore third-party sites that charge a fee to file the same free form on your behalf, which is the standard trap around any digital arrival card.

The notable exemption matters for this airport in particular: Singapore citizens are exempt from the MDAC, including at the Johor land crossings, as are Malaysian permanent residents and diplomatic-passport holders. Everyone else filing visa-free entry still needs to submit the MDAC. Do it in the days before departure; leaving it until you are at the gate, where connectivity and time are against you, is how people end up filing it in the immigration queue.

The entry requirement for most visitors comes down to exactly two things: a passport that qualifies for visa-free entry (or an eVisa if it does not), and a filed MDAC. There is no separate pre-travel authorisation to buy and no other paperwork to chase.

🚌 3. The AA1 Shuttle, Grab, Taxis & the Singapore Connection

The airport is about 22 km northwest of central Johor Bahru, so every option below is a real ride rather than a quick transfer.

⭐ Causeway Link AA1 — the cheap option

The Causeway Link AA1 shuttle runs non-stop between the airport and JB Sentral, the central transport terminal in downtown Johor Bahru, for a flat RM8 one way (about US$2 / €1.75, late May 2026). The ride takes roughly 50 minutes. Buses run at roughly hourly intervals across the daytime — broadly 09:00 to 20:30, with the last departures in the evening — so the shuttle is a daytime service, not an all-hours one. You can pay cash (exact fare helps), by Visa/Mastercard, or with a local ManjaLink card onboard; tickets are also sold at the Causeway Link counter in the airport’s AeroMall. JB Sentral is the useful drop: it sits beside the City Square mall and is the springboard for cross-border buses into Singapore.

The catch is the schedule, not the price. Because the last shuttle leaves in the evening, a late arrival or an early-hours departure leaves you reliant on a car.

📱 Grab & 🚕 Taxi

Grab, the Southeast Asian rideshare app, is the practical door-to-door option and the one most foreign visitors use — the fare is set in the app, which sidesteps the haggling. A metered or coupon taxi from the official airport counter is the alternative. Either runs noticeably more than the RM8 shuttle. The trap is the same as at any airport: take a car from the official rank or the app, not from anyone approaching you inside the terminal offering a ride, where the price is whatever they decide. After the AA1 shuttle stops for the evening, a car is the realistic way into the city.

🇸🇬 The Singapore connection

This is the reason many people use Senai at all — it is a cheaper way to reach Singapore than flying into Changi. There is no direct bus from Senai Airport into Singapore. The route is two legs: take the AA1 shuttle to JB Sentral, then a Causeway Link cross-border coach (the CW services) from there through the Malaysian and Singaporean checkpoints to Woodlands on the Singapore side. Budget for the immigration queues at the causeway, which can be slow at peak times and on weekends, and which are entirely separate from anything that happened at the airport. The whole airport-to-Singapore journey, transfer and border included, runs to around two hours in normal conditions and longer when the crossing is busy.

🛋️ 4. Lounges: Which Card Gets You In

Senai’s main lounge is the Plaza Premium Lounge, which serves both international and domestic departures from a single location airside (on the upper level, past security). It runs long daily hours — broadly 05:00 to 23:00 — which covers most of the schedule. Priority Pass is accepted here. Plaza Premium lounges commonly also sit on the DragonPass and LoungeKey networks and accept pay-per-use walk-ins, but acceptance varies by card and changes, so check the specific terms on your own card against this lounge rather than assuming network-wide access. Walk-in entry is sold; the price varies and is best confirmed at the desk on the day rather than quoted from a stale figure. Malaysia Airlines premium passengers have their own lounge access via the airline. For a budget-carrier airport, one solid contract lounge with a Priority Pass door is a reasonable result — do not expect a deep bench of options.

🍜 5. Food at Senai & in Johor Bahru

The terminal’s food is functional rather than a destination — the usual airport mix of local kopitiam-style stalls, fast food and cafés landside, with a thinner offering once you are airside. It does the job between flights; it is not a reason to arrive early.

Johor Bahru itself is the better meal, and it has a specific reputation worth knowing. JB is a serious food city, partly because Singaporeans cross the causeway precisely to eat here, where the ringgit makes everything cheaper than at home. The local staples are the Malaysian canon — laksa, char kway teow, nasi lemak, bak kut teh (the pork-rib herbal soup that has a strong Johor following), and the city’s street and hawker centres around the downtown and the night markets. If you are passing through with time, the food is in the city, not the terminal — though the layover maths below decides whether you can reach it.

💡 6. Layover Reality: JB, Singapore, or Stay Put

Senai is mostly a point-to-point airport, so true international layovers are uncommon — but the question still comes up, and the honest answer turns on how long you have and which side of the border you want.

Johor Bahru city is reachable but not instant. The AA1 shuttle is about 50 minutes each way to JB Sentral, runs only on its daytime schedule, and then you need a return buffer plus check-in and security. A round trip to downtown JB — City Square, the central food streets, JB Sentral’s surroundings — realistically needs a layover of around five to six hours before it stops being a gamble against your boarding time, and only during the shuttle’s operating window. On anything shorter, or outside the shuttle hours, stay at the airport.

Singapore on a layover is, for almost anyone, the wrong call. The two-leg journey (shuttle to JB Sentral, then a cross-border coach through two sets of immigration to Woodlands) runs around two hours one way in good conditions and considerably more when the causeway is congested — which it routinely is at peak and on weekends. Add the return crossing and the airport buffer and you need most of a day with margin to spare. A short connection cannot absorb the border queues, which are unpredictable by design. If your trip is built around Singapore, fly into Senai as your arrival airport and cross deliberately with time in hand — do not try to do it on a tight layover.

Under about four hours, stay in the terminal. The 22 km each way to JB plus the border friction toward Singapore leaves no room for anything but a wait at the gate.

🔧 Practical Notes — Connectivity, Currency, Border

Currency. Malaysia uses the ringgit (MYR, RM), trading at roughly RM3.97 to the US dollar and RM4.62 to the euro in late May 2026. Cards are widely accepted in JB’s malls and larger places, but cash is still useful for the AA1 shuttle, hawker stalls and small vendors. Airport exchange counters give a poorer rate against a markup, so change only what you need at the airport and use a city ATM or pay by card for the rest. If you are heading to Singapore, note you will be switching to Singapore dollars across the border — keep ringgit for the JB legs.

Connectivity. Malaysia does not block the usual international apps, so a roaming plan or a local or regional travel eSIM works normally. Grab in particular needs working data to be useful, so sort connectivity out before you leave the terminal. A Malaysian prepaid SIM is cheap if you are staying longer than a connection.

Border. Re-read section 2 before you fly. The single most common Senai mistake for a non-exempt visitor is not filing the MDAC in the three-day window before arrival — it is mandatory, free, and quick, and it is far easier done at home than in the immigration hall. Singapore citizens are exempt; nearly everyone else is not.
