Travelers looking to save money on airfare over the Thanksgiving holiday might want to consider getting in early and leaving much later.

Travelers can expect to find the lowest prices if they fly out on Monday, Nov. 20, and if they return on Wednesday, Nov. 29, according to a report by Massachusetts-based airfare prediction app Hopper and Rhode Island-based InsureMyTrip, a travel insurance research firm.

At midweek this week, domestic flights for Thanksgiving were averaging about $322 for a round-trip ticket. That’s about 12 percent higher than the $288 average cost of tickets at this time last year.

Of course, as the holiday gets closer, airfares will only get more expensive. According to the report, the cost of airline tickets for Thanksgiving weekend last year increased by about $1 per day between 15 and 25 days prior to departure. In the final two weeks before the holiday, prices started to spike at $10 per day.
