Hmmm, next week's LIS flights are both red (Outbound and return) and coming back on the Sunday, the only flight showing as bookable is 07:00ish which does not sound fun after a wedding.

Plenty of TAP availability currently but I see the helpful link provided elsewhere suggests "London to/from Portugal where no same day BA alternative".

Given < 14 days notice we'd be returning home some 8 hours earlier than wanted so compensation should apply (I think) BUT can this be used to leverage an XFR onto TAP or will we have to go the tedious route of booking ourselves and trying to reclaim?
