Senai (JHB): shuttle AA1 to JB Sentral, then Singapore

Causeway Link AA1 runs non-stop from Senai to JB Sentral in 50 minutes for 8 ringgit. From JB Sentral, CW1, CW2 and CW5 cross into Singapore.

  • The airport bus is the Senai Airport Shuttle, route AA1, run by Causeway Link.
  • Non-stop between the airport and JB Sentral, taking 50 minutes.
  • A one-way fare is 8 ringgit.
  • From JB Sentral, departures are hourly from 09:00 to 19:00, plus a last one at 20:30.
  • Pick-up at the airport is at the end of the bus platform, and the Causeway Link counter staff will confirm the bay.
  • JB Sentral is the gateway to Singapore. From there CW1, CW2 and CW5 cross the causeway to Kranji MRT station, Queen Street Terminal and Newton Circus.
  • You clear Malaysian immigration at CIQ First Link, about a 15 minute walk from JB Sentral, then Singapore immigration at Woodlands Checkpoint.
  • JB Sentral is also the KTM railway station, for the shuttle train to Woodlands and for trains north.

The shuttle

  • Route AA1, the Senai Airport Shuttle, is the direct link between Senai International and JB Sentral in central Johor Bahru.
  • It is non-stop and takes 50 minutes. Departures from JB Sentral are on the hour from 09:00 to 19:00, with a final run at 20:30.
  • One way is 8 ringgit, which is the cheapest way into the city by a wide margin.
  • At the airport, pick-up is at the end of the bus platform. Ask the Causeway Link counter staff, because the bay can move.

The Singapore connection is the point

  • A lot of people fly into Senai precisely to reach Singapore cheaply. JB Sentral is where that happens.
  • CW1, CW2 and CW5 run from JB Sentral over the causeway. Between them they reach Kranji MRT station, Queen Street Terminal and Newton Circus.
  • The border is done on foot. Malaysian exit formalities are at CIQ First Link, about a 15 minute walk from JB Sentral, and Singapore's at Woodlands Checkpoint. You get off the bus, clear immigration, and get on the next one.
  • Allow much longer than the map suggests at weekends and public holidays. The causeway queues are legendary.

The other way out

  • JB Sentral is also the KTM railway station. The shuttle train to Woodlands in Singapore runs from here, and it is far quicker than the bus when you can get a seat, but it books out.
  • Long-distance KTM trains north to Gemas and on to Kuala Lumpur also start here.

The airport

  • Senai is about 25 km north-west of Johor Bahru, and it is Malaysia's southern gateway.
  • It is mostly a domestic and regional airport, with AirAsia and Malaysia Airlines links to Kuala Lumpur, Kota Kinabalu, Kuching and a handful of nearby countries.
  • Changi is an hour and a half away by road and serves everywhere Senai does not, so the two are alternatives rather than rivals.
