Back-to-back SDC possible on LHR-JFK for EXP?
Hi, I'm wondering if any EXPs have experience changing a flight to more than 24 hrs later by trying to get multiple SDCs in a row.
Let's say I have a return segment (LHR-JFK) of a partially flown ticket scheduled for April 10 in discount econ class with no SWUs applied.
I know that I can try to SDC for a flight within 24 hrs and if there's availability move it to the 11th--but is it possible to do it back to back (and maybe even once more) in order to fly, say, on April 12 or 13 instead of the 10th?
I know some people used to do this successfully on UA when I was a 1k there.
Just wondering what the rules are and what others have managed to do?
thanks
