10 Cheapest US Cities To Fly to This Fall
Travel isn’t cheap at the best of times, but new research from Dollar Flight Club found that you could save between 15% and 60% on domestic airfare if you fly in September or October. That means a flight that would have cost $500 in the summer could be as low as $200 in the fall ($425 on the higher end).
The booking window is everything. For September and October trips, book 4-8 weeks ahead. Thanksgiving travelers should grab tickets 24-59 days early to dodge the price surge. Miss the window and you'll regret it.
