I have a question. I am traveling from PER to OSL via BKK with Thai Airways tomorrow. I was thinking of trying at the airport in BKK to spend my miles to upgrade to business class.
If I get an upgrade, do I still earn miles for that trip. If so, is it economy miles (that would be my guess), or business class miles? For me, the miles are more important than the upgrade, as the miles would get me star gold.
Lastly, if I could upgrade and still get miles, could I use miles from the TG account, and have my miles credited to my TK account. It's with TK I can get gold, but its with TG that I have sufficient miles for an upgrade.
