Speaking of Spirit Airlines and, everyone's favorite, fees: Starting November 1, passengers who do not print out their own boarding pass can tack on an additional $5 fee for the privilege of having an agent print one for you upon arrival at the airport. Says Spirit, "Customers who booked their travel before June 21, 2011 and travel after November 1, 2011 will not be charged the above fee."

Passengers with a printer and a computer handy can avoid fees by checking in online and printing boarding passes at home. As of June 26, check-ins at airport kiosks will also incur a fee of $1.
