Nolan writes: It's been said before, but Spirit Airlines "cheap" ticket prices are deceiving. They typically have airline tickets for a cheaper price than other airlines, from 50 to 100 dollars lower sometimes. But the baggage fees. Checking a bag at the gate is $100. Carry-on luggage has additional fees. They have to make up the cost for the lower price of the ticket vs. extra weight of baggage, but the additional cost can make the trip more expensive overall than a more expensive ticket from a different airline. Just a tip for anyone traveling this holiday season.
