Is it cheaper to buy a plane ticket from STL to ILG last minute?

If you'd rather err on the side of caution, book well in advance of your departure date. In fact, Expedia has some of the biggest deals up to a year in advance. If your favorite carrier hasn't released its airfares yet, check back regularly as offers are updated on Expedia all the time.
