What terminal will you be arriving in and departing from?
This will make a difference as to which lounges/alliances you can access.
You can not hop airside between terminals at lhr if you do not have a boarding card for that terminal.
Do you have elite status with an alliance?
You best value for money (if u have no status) instead of wasting 10K and 34 POUNDS ($54- that's how much the club ba reward saver fee is- if even available) is to buy an admirals club pass on ebay for $24.
The admirals club at lhr terminal 3 is one of the best aa lounges and the best value for $24.
You could make the $24 back just by drinking their complimentary single malts!
Can you use the AA passes you get with the Citi cards?
I have those.
I am not flying AA - Is that a problem?
I do have the Amex platinum but no PP as the plat is canceled.
No elite status with any airline worthwhile.
Thanks.
as a side note, anybody ever heard a time limit to hang out in a lounge?
