Senai International Airport (JHB) — Airport Guide 2026
AirAsia runs an operating base here, which means Senai is first and foremost a low-cost domestic and regional airport — and, for travellers willing to cross the causeway, an occasionally cheaper back door into Singapore than flying into Changi.

🏢 The Terminal — One Building, One Carrier Base
Senai runs from a single main passenger terminal: domestic and international departures share the same building, and there is no inter-terminal transfer to plan around. A separate business-aviation terminal handles private traffic. The scheduled passenger operation is compact — the 22 km to central Johor Bahru is the friction, not the airport layout.
AirAsia’s operating base shapes the schedule. Most flights are low-cost domestic routes and short-haul regional services, with AirAsia’s Indonesian and Thai sister operations adding regional Southeast Asian points. Malaysia Airlines, Batik Air Malaysia and Firefly operate alongside. The airport handled roughly 3.4 million passengers in 2024, predominantly domestic, with international numbers jumping over 50% year-on-year — which is the pressure behind the current expansion works.
🔨 The 2026 Expansion
Senai is mid-build on an upgrade: a new terminal building, runway works and cargo infrastructure aimed at lifting capacity toward roughly 10–12 million passengers a year. Malaysian airport construction timelines move, so check which terminal your flight departs from before you travel rather than assuming whatever configuration you find online is the live one.
⚠️ Self-connections require time
Senai is a point-to-point low-cost airport — no through-checked baggage on self-connections. You will clear immigration, collect your bag and re-check it for the onward leg. Build the full border-crossing time into any connection, not just the airside transfer.
🛂 Border & Visa — Two Things to Get Right Before You Land
Two things govern arrival at Senai: whether your passport qualifies for visa-free entry, and the digital arrival card most visitors now have to file before landing.
🌍 Visa-Free Entry
Malaysia grants visa-free entry to a long list of nationalities. Citizens of the United States, United Kingdom, EU member states, Australia, Canada and Japan enter without a visa for up to 90 days. Chinese and Indian nationals were added to the exemption list in recent years. A separate band of countries gets 30 days visa-free; travellers outside either group apply for an eVisa online before flying. Because the allowance varies by passport — 90 days, 30 days or eVisa — check your nationality’s current status against the Malaysian Immigration Department before booking rather than assuming the 90-day figure applies to you.
📱 The MDAC — File It Before You Fly, Not in the Queue
⚠️ MDAC: the most common Senai mistake
Malaysia requires most foreign visitors to file the Malaysia Digital Arrival Card (MDAC) online before arrival. The window opens no earlier than 72 hours before you land. It is free on the official Immigration Department portal. Third-party sites that charge a fee to file the same free form are traps — they’re not rare, and they’re not official. File it in the days before departure; leaving it until the boarding gate, where connectivity and time are against you, is how people end up filing it in the immigration queue.
The notable exemption for this particular airport: Singapore citizens are exempt from the MDAC, as are Malaysian permanent residents and diplomatic-passport holders. Everyone else entering visa-free still needs to submit it.
For most visitors it comes down to two requirements: a qualifying passport (or eVisa), and a filed MDAC. No separate pre-travel authorisation to purchase, no additional paperwork.
🚌 Getting Into the City — Shuttle, Grab and the Singapore Two-Step
The airport is 22 km northwest of central Johor Bahru, which means every option below is a real journey, not a five-minute transfer.
⭐ Causeway Link AA1 — the cheap option
🚌 AA1 Shuttle to JB Sentral — RM8, ~50 min
The Causeway Link AA1 runs non-stop between the airport and JB Sentral — downtown Johor Bahru’s central transport terminal — for a flat RM8 one way (about US$2 or €1.75 at late May 2026 rates). The ride takes roughly 50 minutes. Buses run at roughly hourly intervals, broadly 09:00 to 20:30, with last departures in the evening. Pay cash (exact fare helps), Visa/Mastercard or ManjaLink card onboard; tickets are also sold at the Causeway Link counter in the airport’s AeroMall. JB Sentral sits beside the City Square mall and is the springboard for cross-border coaches into Singapore.
The catch is the hours, not the fare. A late arrival or early-morning departure leaves you relying on a car — the shuttle is a daytime service.
📱 Grab and Taxi
Grab is the practical door-to-door option and the one most visitors default to: the fare is fixed in the app before you confirm, which removes the haggling. A metered or coupon taxi from the official airport counter is the alternative. Either costs noticeably more than the RM8 shuttle. Take a car from the official rank or the app — not from anyone approaching you inside the terminal, where the price is whatever they decide.
🇸🇬 The Singapore Connection
🇸🇬 No direct airport–Singapore bus
There is no bus running directly from Senai Airport to Singapore. The route is two legs: AA1 shuttle to JB Sentral, then a Causeway Link cross-border coach (the CW services) through the Malaysian and Singaporean checkpoints to Woodlands on the Singapore side. The causeway immigration queues are separate from anything at the airport, and they run slow at peak times and on weekends. In normal conditions, the whole airport-to-Singapore journey runs to around two hours. When the crossing is congested — which it routinely is — it runs longer.
🛋️ Lounges — One That Works
Senai’s main lounge is the Plaza Premium Lounge, airside on the upper level past security. It serves both international and domestic departures from a single location and runs long daily hours — broadly 05:00 to 23:00 — which covers most of the schedule.
🛋️ Plaza Premium Lounge — Priority Pass accepted
Priority Pass works here. Plaza Premium lounges typically also sit on the DragonPass and LoungeKey networks and accept pay-per-use walk-ins, but whether your specific card accesses this lounge depends on card-level agreements, not just network membership. Check your card’s terms against this specific lounge rather than assuming access. Walk-in entry is sold at the desk; the price changes, so ask on the day rather than relying on an old figure.
Malaysia Airlines premium passengers have their own access via the airline. For a low-cost carrier airport, one solid contracted lounge with a Priority Pass door is a reasonable result — do not arrive expecting more than one option.
🍜 Food — In the Terminal and Worth Hunting in the City
The terminal’s food offer is functional: kopitiam-style stalls, fast food and cafés landside, with a thinner selection airside. It will feed you between flights; it is not a reason to arrive early.
Johor Bahru is a better meal. JB has a specific reputation as a food city — Singaporeans cross the causeway to eat here, where the ringgit makes the same dish considerably cheaper than it would be at home. The local hawker and street-food staples are the Malaysian canon: laksa, char kway teow, nasi lemak and bak kut teh, the pork-rib herbal soup with a strong following in Johor. The hawker centres and night markets around the downtown are where the eating happens. If your layover gives you time in the city, the food is in JB, not the terminal.
💡 Layover Reality — JB, Singapore or Stay Put
Senai is mostly a point-to-point airport, so genuine international layovers are uncommon. When the question does come up, the honest answer depends on how long you have.
Johor Bahru city is reachable but not instant. The AA1 is about 50 minutes each way to JB Sentral, and it runs on a daytime schedule only. A round trip into downtown JB — City Square, the central food streets, the JB Sentral 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.
⏱️ Layover maths for JB city
AA1 to JB Sentral: ~50 min each way. Return security buffer: ~45 min. Minimum viable layover: roughly 5–6 hours, during shuttle hours (09:00–20:30 broadly). Under four hours, or outside those hours, stay at the airport.
Singapore on a layover is, for almost anyone, the wrong calculation. 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. The causeway queues are unpredictable by design; a tight connection cannot absorb them. If Singapore is your destination, arrive at Senai deliberately and cross with time in hand.
⚠️ Under four hours: stay airside
The 22 km each way to JB plus the border friction toward Singapore leaves no room for anything but waiting at the gate on a short layover.
🔧 Practical Notes — Currency, Connectivity, Border
Currency. The Malaysian ringgit (MYR, RM) trades at roughly RM3.97 to the US dollar and RM4.62 to the euro at late May 2026 rates. Cards work in JB’s malls and larger venues; keep cash for the AA1 shuttle, hawker stalls and smaller vendors. Airport exchange counters charge a markup — change only what you immediately need at the terminal and use a city ATM for the rest. If you are heading to Singapore, you will switch to Singapore dollars across the border; keep ringgit for the JB-side legs of the journey.
Connectivity. Malaysia does not block the usual international apps and sites, so a roaming plan or travel eSIM works normally. Grab needs live data to be useful, so sort connectivity before you leave the terminal. A Malaysian prepaid SIM is cheap for stays longer than a transit.
Border. The single most common mistake for a non-exempt visitor is not filing the MDAC within the 72-hour window before arrival. It is mandatory, free and takes a few minutes, and is far easier done at home than in the immigration hall. Singapore citizens are exempt; nearly everyone else is not.
