Booking domestic flights online
I am soon to travel to Padang in Indonesia, but will fly to Jakarta as it seems to be the cheapest way. This will mean a domestic flight to Padang.
Domestic flights are pretty cheap, with the one I plan to get coming in at under £30!
The piece of advice that I want to give is to book at least a few days in advance. I tried to book mine at the last minute, but was unsuccessful as the booking online needs to be done at least 48 hours in advance at Lion Air and further in advance on some other websites.
Just for your information, here are some airline websites that seamed good enough:
