I notice in the change email, it says Explorer Club passes are only valid and entry only allowed 3 hours before a flight. Is that going to be a hard and fast rule, because if so it's kind of worthless for me. Because I sometimes like going in early or because I just book business flights. The only benefit I currently get is priority boarding when in Economy. Is paying for priority boarding per flight something that is available, like how you can pay for Club passes, economy plus, etc? It may be worth it to keep the $95 Explorer card even though I don't travel much.
