What I would do is get to your departure airport earlier than usual. Speak nicely to the airline desk staff and point out what has happened. You may find they can input your middle name free of charge. Someone did that but another person was charged $5 USD. Either way you will then have peace of mind Josh!
Absolutely doable! Bangkok Bank are most definitely ‘foreigner friendly’. They like to sell personal accident insurance as the staff get commission. If you have no other form of insurance it’s worth buying at around 5,000 baht. Fees are similar. You pay an annual account maintenance fee and fee for debit card if you request one.
I know we’re talking about UK but my sister-in-law was refused a tourist visa for Australia. One of the ‘reasons’ they gave was that money had only recently been deposited into her savings account. This apparently indicates to them that she normally doesn’t have any!
Flew Thai Airways from Munich to Bangkok September 2023. Check-in staff required sight of return/onward ticket or, ‘some sort of visa’. I had extension from Non-O (Retirement) Visa and reentry permit which I showed them.
My second leg (Bahrain to Bangkok) was cancelled due to a death on the aircraft. We were provided with refreshments, transportation and overnight accommodation. Didn’t actually incur any loss though.
