Airline: DL
From: JFK
To: KEF
Fare Class booked in: T, U
As a plat, DL will give me ~5k, while AS ~2.8k. Considering this will be my only flight under this DL FFN, I'm leaning towards AS, as 5k DL sitting in an abandoned account won't do me any good.
Here's my question: the flight wasn't booked from the DL account; the DL FFN was added later. If I now put in my AS number instead, will the plat benefits disappear, or the PNR will still show as a plat account?
Or is all this not worth it and just credit to DL...
