I have a flight arriving mid afternoon into CGK. I'm still undecided whether to fly on to Bali the same day, or get an airport hotel and fly on the following morning.

It was suggested that GA are the best of the airlines that fly between the two airports, and they have evening services at 5:55pm, 6:45pm and 9:35pm. The 5:55pm flight should give me plenty of time to clear imigration, change terminals and catch the DPS flight, but what happens if I miss it? Garuda describe the fare ECO Flexible, with a fare basis of YOWID. However, I can't find any fare rules that cover cancellations or rebooking onto the later service that same day.

Does anyone know what the consequences are of trying to change to an alternative flight. Is it just a rebooking fee, or do I have to buy a new ticket?
