I joined the $9 club fare about 2 and half months ago. Usually every Tuesday and Friday they come out with their special promotions. And I have noticed (because I have been obsessive in looking all day!!) that it generally appears on their website at 3pm (EST). Anyway, the fares for the $9 club fare only are not snagged nearly as quickly as the regular special promos (non-$9 club fare). Almost a month ago, I booked 5 tickets from DTW to ORL for $84!! including taxes and fees.

Yes you do have to pay for your luggage, but so what at that awesome price. If you pay to check your luggage online (you can do it up to the day you leave) it is $5 each way ($10 round trip) for each piece of luggage. Otherwise you pay $20 for each piece at the airport. Everyone is allowed only one carry-on not including a diaper bag, purse, laptop etc. Not sure if that changed since the person who posted above last flew Spirit. Definately beats driving with 4 little ones!! We are heading to WDW this Monday.
