Before you pick a lounge

Check which terminal your flight leaves from. A lounge in another terminal can mean a second security screening.
A lounge before security means screening after your visit, so leave time.
Where we don't know a lounge's security side or exact entrance, we say so rather than guess.

Lounges and other experiences are counted separately, and records of the same lounge from different sources are merged into one. Card access counts only paths we've reviewed against issuer and program terms.
