It's so long since I have done a POUG (pre-Covid I think!) that I can't remember when they generally get offered? I have a LGW-AMS coming up in around 3 weeks and returning RTM-LCY a few days later. Then in Feb I have a LGW-TRN and returning MXP-LHR.
At the moment, all of these sectors are showing a pretty high price to upgrade.....circa £140 for each, which I guess is just a standard upgrade and not a POUG offer. Appreciate they can be offered at any time from 48 hours after booking but is there a usual good time to start looking, ie X days before flight for the much cheaper POUG pricing?
