Thanks Kiwi Flyer and Kawoh.
Kawoh - do you mean that lax-jfk on ua leaves from T7 or T8 and the only lounge there is the UA lounge?
I guess then what you mean is that you could not leave T2 and use the lounge there before heading over to T7/T8?
I find the NW lounge dreadful - are the UA lounges in T7/8 any better?
Thanks!
