No direct flight. Only 2 airlines fly direct Melb - Bangkok - Thai and Jetstar, the latter which I won't again fly. Scoot is probably the cheapest but not by enough to dissuade me from booking a direct flight. I just don't understand the high prices at the lowest point of the Thai tourist season, particularly when Google claims June to be the cheapest month generally to fly to Thailand.
May was cheaper than June so I imagine April is cheaper still, though still much more than $934 next month. Also Sydney would be cheaper than Melbourne.
Pretty sure if you withdraw money and it comes out but you fail somehow to get it (forget etc) it returns inside and you are not debited. Perhaps that happened to you.
You're a bit rude for someone seeking advice! I don't understand why anyone would want to bring a dog for a short visit. From the moment you step off the plane it will be a hassle. This is not the dog friendly environment you'd find back home.
