Better airfares for off-peak dates

At American, the cheapest price on a Thanksgiving trip from New York to Las Vegas and back was a hefty $1,095 for travel on Nov. 21, the day before Thanksgiving, and returning on Sunday, Nov. 25. Those are the peak days for those holidays. But change your itinerary to leave Thanksgiving Day and return the following Tuesday, and the Las Vegas getaway costs only $335 on American.
