Hello I’m having my first trips on LATAM next month and I’ve found a couple of snags that others might be able to help with.

the app sold me 2 premium economy tix mde-lim-eze which I chose mainly for the baggage allowance and comfort for night flight. However it only shows one available prem seat on the LIM-EZE sector and I can’t select the other seat anywhere in the cabin. It’s an overnight sector so I’d like to know where I’ll be seated. Common problem?

one ticket through but will I have to recheck bags in Lima? 2.5 hour layover.

the LATAM app seems to decide it won’t accept your frequent flyer number in one booking but will in another booking, whether I put my BA or VS one in. Is it usually temperamental? And will I be able to put it in at checkin? I’m after the VS tier points more than anything

thanks in advance for help
