I can't decide whether this is a good deal, or if I should keep looking. We are a family of 5 flying Detroit to Orlando Friday, April 20th. So far the best I can find is $986.60 return through Southwest. Should I just book it or keep looking for a cheaper flight through Spirit or AirTran? Our dates are not flexible. I don't want to book it only to have Spirit come out with a $29 flight!!
