From Chicago Breaking Business (via Daily Kos of all places) Spirit Airlines to try $45 fee for a carry-on bag
(Parenthetically this is a terrible name for a website, Chicago "breaking business", if so business should move elsewhere)
"Spirit Airlines will charge as much as $45 each way for a carry-on bag, adding a fee that bigger airlines have yet to try. The charge will apply to bags in the overhead bin. Personal items that fit under the seat will still be free.
The new charge is $45 if paid at the gate, and $30 if paid in advance. It begins Aug. 1. Spirit says a new fare reduction means most customers won't really pay more to fly.
It says having fewer carry-on bags will help empty the plane faster. Spirit also charges to check luggage.
Spirit mostly flies out of Florida to Latin America. Even though it's a minor player, bigger airlines are likely to watch to see whether customers are willing to pay for carry-ons."
First they charge you for baggage that is checked, now they charge you for bags that are in the overhead. I suppose it will be cheaper to just buy clothes at each end and dump the suitcases if this persists. It is almost enough to make someone want to take a train or ride a bus. Someone once called long distance phone companies "billing machines with a network attached", it seems airlines are moving in that direction.
