Hello everyone. I'm looking at doing some nested back to back flights from Glasgow to London in October. The prices keep changing but it should be about £2 per tier point. Does anyone know if it Is it feasible to fly in and out of Heathrow T5 with a 1 hour gap? I've read on another thread that I need to scan my boarding card at Heathrow T5 30 minutes before the flight?

Thank you for your help,
