A couple of days ago I set up an itinerary, but put it on the "next day midnite" holding pattern, complete with its own PNR. Next morning, after confirming a meeting time, I went back to .bomb to check flight times & found an earlier outbound with the same return that actually cost approx $200 less per pax for the RT. So I booked it, getting a totally different PNR. Couldn't find a way to cancel the original held itinerary on line, so I called the 1p desk & got it taken care of. The rep said something about a change fee, but since the original one was on hold, that didn't apply. So here's the question: assume you have a held reservation, but want/need to make changes to it; can this be done on the same PNR at no cost? Especially, in a sense, involving a refare. Or would a change fee apply? [somehow the analogy of regaining virginity comes to mind]
