Typically, when it comes to booking holiday flights, waiting until fall to book flights for winter yields the best prices.
“Factors such as seasonality will alter how long you should be researching flights,” said Sentosa. “For example, CheapAir found that the cheapest flights were around 67 days before a summer trip, 94 days for a winter trip, 84 days for spring and 89 days for fall.”
Late September/early October have always been the best times to begin booking. If you aren’t able to find a good price before late September, then booking around then will still likely offer you discounts on flights.
