We arrive on a late Saturday night, 10:45 PM from Chicago on American Airlines #90 (Terminal 3).
We leave next day, Sunday morning at 7:00 AM from Heathrow on British Airways #638 (Terminal 5).
Any advice would be appreciated.
You cannot get into Terminal 5 until the morning of your flight. Security opens about 5.30 am.
You are not supposed to go into the "wrong" terminal so sleeping in Terminal 3 would be discouraged (if it's even still possible?).
Therefore you might end up stuck outside next to the check in counters for 7 hours—rather unpleasant!
I advise you get a hotel room near Terminal 5.
