Hi all, taking my first flight in over 3 years next Sunday. It’s the BA 7am MAN-LHR followed by LHR-SFO all in Club. We have 1 checked bag total and a carryon each. MAN is the problem given the potentially horrendous security queues (BA still at T1) especially at the start of Easter school holidays. I’m aiming to checkin online but given it may not work at what unearthly hour would you arrive at MAN for checkin and what time does BA checkin actually open. Thanks for your views.
