Mom2Casey, just book it. Keep checking religiously, especially as it gets closer, and if the fares go down it is not hard to change it and get credits. You would have to use the credits (which are just the dollar amount of the difference) within a year, however. You never know what can happen, so at least get the flights you want, and non-stop is great (no wondering about holdups at other airports). Just my opinion, as asked!
