Spirit Airlines Inc. employees helps customers at the check-in counter at the Fort Lauderdale International Airport in Fort Lauderdale, Fla. - 

This final note today, which comes to us courtesy of Spirit Airlines.

Starting in November, should you need to carry a piece of luggage onboard a Spirit flight and neglect to pay in advance of arriving at the gate -- that'll be $100 please.

A C-note for each bag, which pretty much forced us to dig into our archives and pull this out from the Marketplace Players -- check out this feature on what else airlines can charge us for brought to you by Rico Gagliano.

The radio show Rico does with Brendan Newnam is called The Dinner Party.

And let us know -- what other charges do you think airlines have up their sleeves?
