Booking your journey from Bilbao Airport (BIO) to Dallas Love Field last minute could save you cash if you're lucky to find a terrific deal. However, airfares typically don't come down in price as the departure date nears. If you wait around, flights could also be sold out or the best seats gone (that could mean the middle seat!). If you'd prefer to play it safe, 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.
