So I tried to check in for a flight on mobile.aa.com from my phone. Selected check-in, went through the exercise of pulling up the reservation, and then found that ... there's NO check-in button! Everything else from www.aa.com (Passenger name, pull-down menu with option of Adult/child under 12, check-in status) etc. is there, but there's no red button containing the CHECK-IN letters.

Anyone else experiencing this?
