What's the earliest you're allowed to check-in before an AS flight? I have an 8:45p AS flight to Mexico, but need to go to the NW WC lounge before it closesat 5:30p to pick up my card. Due to meetings, I have to work until then and am only free in the morning until around lunch to do an early run to the airport.

My thought was to run to SEA at lunch, check-in with AS, run to the S gates and pick up my card. Then go back to work and return to the aiport later that evening for my flight.

Doable?? Can I check-in 8+ hours early? Can I check a bag that early? If not, can I check-in early then check a bag later that evening?

Thoughts? Ideas? Any way I can pull this off?
