Part 3. Exercise
Never again. I used Travelocity to book a flight out to Vegas for a business trip. This was the only flight with the times I needed so I booked it. I didn't think it was all that great a deal either. And Travelocity didn't warn about all the fees you will incur when you do check in with Spirit (which I really think they should do since they aren't like other airlines).

I'm pretty sure if you sneezed and asked for a tissue, a flight attendant would charge you for it. I am a really anxious flier, so for me I need to sit in the window and see what's happening. I checked in like I would with any flight to pick my seat, and if you want to actually choose your seat you pay at least $18 for it. Otherwise you can let them assign you and maybe you won't be shoved in the middle. I don't like this, no other airline does this. It's a rip off. Bags were also a few dollars more, and the weight limit is 10 lbs. less than every other airline. Strike two. Between picking a normal seat (nothing special...and don't expect leg room) and checking my bags it was about $100 extra. What a rip off. Oh, and if you want to carry-on instead of checking, you will pay about $100, so don't waste your money. They will find a way to make you pay. They also destroyed my luggage, and this suitcase is pretty indestructible.

The leg room is non-existent, and you feel like you are riding a greyhound in the sky. The plane seems like it is about to fall apart at any moment, and if you feel cramped in a regular airplane, this will make you feel claustrophobic. The only awesome part was that they had drink deals. One drink for $8 or two for $11. Worth it to get two if you are flying a long distance. And they come around twice during the flight.
Answer:
NEGATIVE
