Hello and thanks in advance for the help. I paid in advance for seats on flight from LHR to Frankfurt seats 8d and 8e in economy. My question is, if checking in right at 30hrs prior to flight with no status, what group will we likely be in and also, can we board together. Ive read about boarding by seat location (window, aisle, middle) but will my companion and I be able to board together? I have the airline app on my phone and they don't. Will obviously download on theirs if needed but curious how this works being it's my first time on this airline. Thanks again for the assist!
