I am booked on a roundtrip )SF0-IAD-SFO and used an RPU on the outbound leg a while ago to ensure I was upgraded (red eye and I want to sleep). I am now upgraded.
It appears I am now going to have to go to LAX first and then do a redeye from LAX to IAD.
All my business flights are done by a travel agency which does not look past the normal agency interface (i.e. they do not see my 1K status and so cannot put me in exit rows, cannot apply RPUs or GPUs etc.). So after they book I always to then go in (or call) and change seating or apply upgrades etc.
So, my main question is: do I need to call and get the RPU cancelled before I have the travel agency change my flights? I have other RPUs so I am fine if it take a while for the RPU to return to my account. But will it do so automatically if the travel agency simply changes my flights? Obviosuly I will have to call or log in after the flight is changed to apply a new RPU sought after upgrade (unless, as the case may be here I am booked in M for this red eye thus getting the 1K M instant upgrade). Just trying to figure out whether I need to first pull my old RPU before having the agency change the flight.
