$50 off Spirit Airlines, extended to July 12 To receive $50 off your next roundtrip purchase, just enter 50OFF in the promotion code box when booking a qualifying flight. All flights must be booked by 11:59 PM ET on July 12 for travel starting from July 13, 2012 through November 14, 2012. Coupon usage also excludes travel between the following (in both directions): Atlantic City to/from Myrtle Beach, Buffalo/Niagara Falls to/from Myrtle Beach, Boston to/from Fort Lauderdale, Detroit to/from Los Angeles, Los Angeles to/from Chicago, New York-LaGuardia to/from Chicago. Factor in the cost of carry on luggage or checked luggage, buy a beverage and a pack of peanuts at the news stand in the terminal, and if you can endure sitting in a seat with 28" of pitch, and if you are less than 6' tall and 250 lbs., this might work for you. It worked for me twice.
