Unfortunately, whilst O/D experience for F and GCH passengers has very significantly improved in recent years, that of transfer passengers (except from domestic) is still very poor. The trick suggested by cws is undoubtedly a way to reduce the frustration, but quite frankly, no transfer passenger in paid F (and arguably no transfer passenger in premium class or with high frequent flyer status) should have to need to find such roundabout ways to have a smooth and reasonably timed transfer.

Transfers from T5 to T3 are even worse as any attempt to exit to reenter is punishing and as HAL employees have a very bad tendency to send non priority passengers to flood the priority queue if the former looks busy so that the latter frequently becomes wholly ineffective.

So personally, I fully agree with ThatT1Feeling and think that it is high time BA started to invest some thought in the experience of transfer passengers (again, except from domestic which is generally well taken care of in my view)
