My ticket is a DL award ticket RNO-SEA-ICN-AMS-PRG so it is all on one ticket.
I am booked on the first RNO-SEA flight of the day... arriving in SEA at 11:15 and trying to catch DL199 at 12:30.
"AS may not be as willing to do that with a Delta ticket"
If it is their responsibility, what choice do they have?
