Use a cab instead.  I can't stress this enough!  I had three full hours to get to the airport for my Monday flight out, and we waited for a full hour, no bus (even though we prepaid!).  We ended up taking a cab instead, and realized that it was THE SAME COST!\n\nOh, and can I get my money back for the fare I didn't use?  Not an option says the lady on the customer service line.\n\nSure, you might think that this bus is a less expensive route, but you would be sorely mistaken when you miss your flight.  You have been warned.
