BA transit at LHR
BA's move to T5 is great news if you are in transit from another BA flight. Present transit from BA international arrival in T5 to BA LDS flight at T1 is a nightmare... I did it last week and decided I would go back to using MAN as that was an easy transfer and contained within T5 - usually walk from inbound a/c and completing formalities takes around 10 minutes.
With a T1 departure, after waiting for the T1 transfer bus and the actual journey to T1 - 20 mins, it took another 10/15 minutes to complete formalities and reach the T1 domestic gate area. Added to that, BA's T1 Domestic lounge (former BM lounge) was third rate to say the very least - as it was lunchtime, would have expected at least some sandwiches, but all that was on offer was cheese and biscuits.
