In regards to the cut-off for handing over checked luggage: per our Conditions of Carriage (www.aa.com/conditionsofcarriage), baggage cutoff is 30 minutes. However, we recommend that customers get to the airport 90 minutes prior to departure if checking bags to ensure adequate time to check in.

Both good questions, Psyflyer. Thanks for asking!
