I saw some comments about using FedEx or UPS for the commute. My question is how can you find out what schedules they run...for example, to find out what their earliest am departures are to selected cities to make an early show time.

I am in the 14th class and am still trying to figure out how the whole commuting thing goes, do many people that commute have to fly to their domicle the night before? Or can many of them get an early am departure to the domicile in time?
PS I will be commuting from ORD
