1. Spirit Airlines: $100 per carry-on bag
Quite possibly the unfortunate wave of the future if enough complacent travelers don't start voicing their opposition, three domestic airlines now charge for your CARRY-ON bags. Spirit wins as gougiest at $40 per bag when pre-planned -- compared to Frontier ($25) and Allegiant ($10). If you don't pay ahead of time, do too much shopping at Hudson News and the gift store, and try to carry on at the gate? That'll be a cool hundred bucks cash money. Thank you, Spirit Airlines, for making capitalism feel so good.
