My personal ranking

1. Cathay. Great seat (only 3 across on the 777, very wide, 3 people could have dinner in one seat, 2 on the seat and one on the footrest). Lounges in HKG are very good. Food is good to ok, service is very good most of the time

2. JAL. Good seat, great service, food good if you like japanese, western choices only average. Lounge in NRT a bit disappointing compared to the flagship lounges of other airlines

3. British: Small seats (14 in the nose of a 747 where 8 to 9 is today's standard), more like a glorified business class, service often with an attitude. Lounge in LHR disappointing (concorde room) and not up to standards of other real F lounges

4. American (no experience with the new F yet). Service usually a miss, seats small (4 across but diagonally, pitch is only about 3 windows where 4 is standard now). No privacy, not enough protection from people walking in the aisle when you try to sleep. Food is business class food. Lounges are substandard.

No experience with the QF in the last few years.

Compared to other airlines:
LH in general has better ground services in MUC and FRA than any oneworld airline, but unfortunately they never drive you to the FCL/FCT in FRA, only from and only when you pick the correct lounge. In MUC they drive you only when your flight does not dock on a finger. The lounges itself are superior to even what Cathay offers. Great food.
TG has the massage and the buggy or escort top/from the FCL, but only when you fly with them. Food is disappointing.
AF drives you from/to the plane in CDG, their lounge also is extremely good.


I would take CX any time, JL also, but would avoid AA and take BA only when there is no better alternative.
This is my personal ranking, others will have differing opinions.
