Hi all,

I'm travelling London-NY and am contemplating doing the 399 upgrade from CW to F (lots of these available when I search for flights). Never flown F before!

A few questions:
1) Do ppl think this is worth the upgrade? I've heard the LCY-JFK route is almost like an F experience (private plane, generous tier points, better immigration)
2) Would AA or BA F be the better option?

Opinions much appreciated!
