Hi all,

I have an Avianca itinerary booked in U-class from JFK-SAL, at 4:40AM on March 25th, then onwards to RTB. This flight would normally earn 50% of miles flown if credited to Lifemiles, meaning I'd earn 2349 miles.

I'm considering applying for a status challenge on United airlines that would give me *A silver status for 90 days. I'm trying to select a starting date for the challenge that will maximize my use of the status.

If I were to change my frequent flyer number on this itinerary to United, however, I'd earn far fewer miles.

If there was a reasonable chance of an upgrade to the business cabin, I'd willingly sacrifice the miles. Does anyone have a sense of whether that is likely on this flight?

Thanks!
