BA have stopped checking boarding passes as you board the aircraft at the door, well the 30-40 domestics my daughter and I take every year, that’s been GLA, EDI, LGW, LHR and LCY, this year. The last point I show my boarding pass is now at the gate to whoever is handling it, Swissport, Menzies & BA. From a person who worked as a dispatcher for BA & BD it took a while to get use to but it has been this way for three years. If you’re regular pax then it’s probably been that you’re so use to showing it, you still do. I also work at various UK airports and have experience of boarding procedures of various companies and some still ask at the door others don’t. It’s also possible that BA has reimplemented the crew checks after the old dears trip to the UK and the nice charge that may have been imposed under the CLA Act, if you say you have recently had to show it again.
