Please bear with this relative newbie,

Finding it difficult to decode this stuff. Find it difficult believe there's not a pair of L seats going north from PUQ to SCL anytime between Feb 20 and March 3 ��

Not a formal wait listing but if we just show up off the MPN PUQ flight on 20th (or say the following day) and there's space in Y in any of the multiple flights, does anyone have a view if we can grab the seats and LA can then flog ours at their leisure? Do local staff have any discretion in such matters? Would a phone call to BA (issuers of our LONE4) be an expensive waste of time?

Many thanks all. Really appreciate the collective wisdom of this forum.
