Dear ex-JFK flyers:

Would you know if the staff working at the BA lounge can help Cathay pax upgrade their tickets using Asia Miles?

I am trying to wait till the last minute before I use my miles to upgrade, hoping that by some dumb luck I might get op-up before using my miles. However, if not then I'll use my miles at the lounge.

I know in HKG all the lounges are very helpful, but not sure if the same is for the JFK BA Lounge.

Thanks.
