Not the same, but checking in with other half and two small people. Boarding passes printed at LHR T5 as we checked in luggage. Went through security, and one of the boarding cards beeped. Agent took all four passes and passports and waived us through. Only when getting to the lounge did we realise we had two boarding passes for my son and none for me. So, I basically got through to airside without a boarding pass. Not great either.
