대한항공 어워드 티켓으로 델타 비행기를 탈때 델타 아멕스로 대한항공에 수수료(텍스)를 델타 아멕스골드로 내면 first bag free 가능한가요? 혹시 일부 구간 upgrade 을 델타아멕스로 pay 하면 어떻게 될까요?

아멕스에는 이렇게 나오구요..

"As a benefit of Card Membership, you can check your first bag free on Delta flights booked with your Card. You can save up to $50 on a round-trip Delta flight per person. For a family of four that's a potential savings of up to $200 per round-trip flight."

델타아멕스로 full payment 라는 말은 없네요..

다른 싸이트에는 이렇게 나오구요..

1.   Do You Have to Pay With the AMEX Delta Card?

NO.  It’s enough to simply have the card in good standing to receive the benefit.

Some cards, like the Chase United MileagePlus Explorer, require you to pay for your ticket with the card to get a free checked bag.  But NOT the AMEX Delta cards!

Just be sure to put your Delta SkyMiles number on your reservation.

혹시 비슷한 경험 있으신분 있으신가요?
