Is that the ridiculous thing whereby they take photos of everybody passing through - creating a nightmare when you've got a slightly hungry toddler who doesn't want anybody to take a photo?Was it a while ago? I flew with them on a return trip Heathrow - Glasgow between the lockdowns in 2020, my license was given a cursory check when I dropped my bag and I did the swish security set up they have at T5.
Found the whole departure/security process at Heathrow a complete nightmare several times and we're now trying to fly from much more pleasant airports such as Bournemouth or Southampton (or anywhere where the security process is actually sensible and geared up to having people pass through rather than robots).
