I was working on a booking for friends and realized that owning the DL AmEX card gives favored availability for domestic awards vs. not owning it. None of the three accounts I tried, including mine, are for anyone with any DL status.
I checked MSP-SEA for 09 July. Not logged in (or logged into an account of someone who does not have the card) only gives 40K mile awards. But once logged into the account of a DL AmEx cardholder, the "I am traveling" button appears and if checked, gives a 25K mile award on one flight that day.
You learn something new every day! One more reason to own the DL AmEx card vs. being FO
