Hello everyone. Quick question-I have a $200 off $1000 Amex offer for Airfrance on my delta amex card. I'm in the market for a couple of RT tickets on delta to london next summer but am hesitating to book through AF. Is it the same pretty much as booking through delta? I want the app upgrade offers and the ability to change the flight if I need to, would I have to do that through AF or will the reservation automatically get transferred to Delta and my only interaction with AF is at the initial booking? Thanks in advance for any guidance!
