u/DepartureReady769

Hi I am planning on travelling SE Asia beginning of next year and know most places require an onward ticket which I have seen most people book using ‘onward ticket’ website which is fine. But some places also require a visa and or entry card which ask for flight numbers and would these need to match up???
The onward ticket is only reserved for 48hr and visas and arrival cards are usually done before.
What’s people’s experiences? - I’m British
I would rather be relaxed and take each day as it comes instead of having a planned route, I obviously would not over stay in any place but I am only going for 3 months and might want to stay some places longery
