Not worth it
To be absolutely honest – there are better places in the world to try and blag access to. On my few visits, I’ve actually found the lounge to be pretty poor in many respects: the lavatories are disgusting and service can be mediocre. There used to be a wonderful barman who would mix any cocktail you wanted - Bozak? - but he left. The sleeping cabanas have gone. The only decent place was the meeting room but now that’s disappeared as well. Personally – I’d much rather stick to the American Airlines first lounge over in terminal three.
