Если мне друг купит билеты со своей карты на самолет Bangkok Airways - могут ли потребовать его карту при посадке на рейс?)

Плохо, что не знаете. В Бангкок эйр в каждом билете написано. Credit Card Restriction As part of efforts to minimize credit card fraud, Bangkok Airways employs a third party fraud prevention operator to audit all payment transactions. During the check-in process at the airport, Bangkok Airways will perform a random check on the credit card used for online payment. If you have paid by virtual credit card, you need to present evidence of the transaction in order to prove ticket purchase. Failure to present the card or proof of payment will result in passengers being required to purchase new tickets for all sectors. Passengers will be denied boarding if found travelling with tickets purchased by the fraudulent use of credit card. Красным выделено.

@Aнна: Давайте тогда спросим тех, кто летел, проверяли у них кредитные карты?

@Nat: Давайте , у меня в Трате проверяли.
