When Should You Book a Flight Last-Minute? Upgraded Points Reveals Best Airlines and Routes for Spontaneous Travelers

Study finds many last-minute fares can be significantly cheaper.

AUSTIN, Texas, April 1, 2025 /PRNewswire/ -- Upgraded Points' newest study challenges conventional airfare booking strategies by analyzing thousands of flights across some of the busiest domestic routes. The data reveals that while some airlines increase prices as departure time nears, other carriers actually reward last-minute bookings with lower fares. Waiting until the last minute to book a flight can be a savvy money-saving strategy or an expensive misstep, depending on routes and airlines.

"When it comes to buying tickets at the last minute, precise timing does matter – but not in the way that most travelers think," said Keri Stooksbury, editor-in-chief at Upgraded Points. "Knowledge is key, and by understanding which airlines and routes offer genuine last-minute savings, consumers can make smarter booking decisions and potentially save a significant amount on airfare."

Study Methodology

To identify the best airlines for last-minute bookings, the study gathered daily Google Flights airfare data for 10 of the busiest U.S. domestic routes over a two-week period, analyzing over 21,000 flights. All "last-minute" fares reflect tickets booked exactly one week before departure. These fares were then compared to established averages from previous airline cost studies to determine how prices shift when booking at the last minute.
