Brexit made paupers of a lot of us who have savings in the UK but live elsewhere.

Simple answer: Ask when you check in for the first flight - they will be able to give you the definitive answer. As for the visa - your situation is exactly what they were designed for.

Please don't. Moving to another country will just make all of your problems seem worse, and the "middle aged guy goes to Thailand to find happiness - then engages in self harm" trope is a real one. $1,000 is not nearly enough of a grub stake to get you established in any profession or job - and you will soon find it gone in the (inevitable) party you have for the few days after arriving. Try to build up at least a years income as savings before you do a life shift like this one.

Be very very careful exactly what you are opening. If they want your marriage cert and wife's details then ensure that it is YOUR bank account and not some sort of joint account.
