When flying from Johor Bahru to Bahrain, the time of day you decide to fly out makes little to no difference towards the overall price you’ll pay on tickets.
Located just 21.9 km from the city centre, Johor Bahru Sultan Ismail Intl (JHB) is the airport most travellers will use when flying to Bahrain from Johor Bahru.
These are just IATA (International Air Transport Association) codes. They are used in aviation to identify and differentiate airports. That’s why a Johor Bahru Sultan Ismail Intl Airport to Manama Bahrain Intl Airport flight would often be abbreviated as a JHB to BAH flight.
