LCY LCY LCY gets my vote....
New Aircraft.
Very, very good crew and catering.
Quiet.
The whole feel is one of exclusiveness and far from crowds.
No Q at Immigration at either end.....
Downside? Possibility of diversion if weather really poor.
LHR?
As a silver travelling CW the LHR club lounge is only ok and usually very busy..
Q up with the other 300 or so passengers (well, join the fast track line and then meet every body on the jetway)
Q for ages to get thro' immigration at LHR and NYC?
Variable crew that can be superb, or feel hard-done by and just do the minimum, even in Premium cabins?
Travel on a plane that could be over 20 years old?
The only plus point for me about a LHR flight is the chance of an operational upgrade, or the offer of a POU to FIRST which would then tip the balance to LHR.
Try LCY, and let's hope that BA expand this superb service. DXB would be good!
