Spirit Airlines, the first carrier to impose fees for carry-on bags, starting in November will charge as much as $100 per bag for passengers who bring luggage to stow in the overhead bin.
It currently costs $45 if you show up at the gate with a carry-on bag. That figure will rise to $100 on Nov. 6, according to baggage fees listed on the airline's website.
Spirit has a dizzying menu of bag fees that are tied to the point in your reservation when you "buy" the option of taking along a carry-on bag.
For example, it will cost $35 for a carry-on bag purchased when you make your reservation, $50 if you buy the option at an airport counter or kiosk, and $100 if you wait until you're at the gate. The airline also is raising some fees for checked baggage, too.
