We will bw flying out from LIS to LHR in January 2026.
I will have my elderly mother with low mobility with me, so I will aim to arrive at the airport as early as possible.
We have checked luggages with us, when is the earliest that we can check in? It won’t matter how early we arrive if we can’t check in until 2h30min before flight, right?
Any insight is appreciated.
Thanks.
