OK it is late and I am crabby. I am planning a trip in a few weeks and I am traveling on Spirit Airlines. I went to their site to make my seat assignments which they would not let me do because I did not book through them online. I booked through American Express. Then when I looked up my reservation it said I did not pay for my checked baggage. Apparently you now have to pay for any luggage you check!!!! I can't believe it!! I know, not a major problem, but it is the point. You pay a ton for a ticket and then they charge you extra to check your luggage!!!
