Give yourself 2 flights that arrive at least 45 minutes before departure! If unable to make it you will receive a miss assignment, then go see the chief pilot who you will present the evidence of the two flights and he will change it to commuting policy. Lately they have been hurting for folks (mainly Captains) that they have been giving them confirmed seats on an AA or AE flight to get them there for the flights. This doesn't happen all the time but when they need you Crew Scheduling will do whatever they can to get you there, if they have reserves they'll give you the middle finger most of the time.
