I've a flight JFK-LAX on Saturday, but with a tight connection in JFK, I'd like to be able to check in online before I start my travel.

I remember before AA always had the check-in box on the reservation page but when trying to check in 24 hours before the flight it wouldn't let you. I'm a bit nervous because I don't see any check-in box on my reservation page now? Did they change it, and will it appear 24hours before the flight?
