how early can you check in at Heathrow?
My wife is flying AA Saturday night Chicago-Heathrow, arriving 11:30 AM Sunday. Then after layover, departs 10:30 pm on BA Heathrow-Tel Aviv.
Question: How early is she allowed to check in for her BA flight? Ideally she's wants to check in for BA flight right away and take a train into London for a while so she can get rid of her bags.
Thank you!
