Can I ask a related question? I didn't find anything when searching the group. So I have this Dr. in my last name (in some countries they will add this to your name after completing a doctorate, not many though). In terms of a PP it's a complete mess, I often get complaints at the airport either because I added the title or not (often times you have no choice anyway in the booking form). Thanks for the tips with the MRZ, so in my current PP that is not part of the MRZ. So you think it is ok to put it as title? In my previous PP it is part of the MRZ. Again, complete mess. Any ideas?
Airplane check-in bags are usually the worst option as for price. The cheapest is usually partial-container loads, yes, but might take several weeks to arrive and you have to find a reliable provider that won't rip you off and have to deal with customs in your country and TH (you'd have to do that too on the flight, ofc you can try to go through the green lane but will not always work, basically illegal if you bring valuable items)
If you are on the east coast of the US Spain is ofc much closer than Thailand. Else you are probably using the wrong search engines, many airlines fly to TH. BKK has 60m passengers a year
