How to Book Cheap Domestic Flights in the U.S.

Tip 1: Plan and Book Early

Planning ahead is key! Lock in cheap fares by booking your domestic flights as early as possible. Last-minute bookings often result in sky-high prices, so take advantage of early deals.

Tip 2: Be Flexible with Travel Dates and Times

Airfares can vary significantly depending on the day and time of travel. Flying on Tuesdays, Wednesdays, or Saturdays, which are often less popular travel days, tends to be cheaper.

Tip 3: Use Flight Comparison Tools

Trip.com offers a smart system to help compare prices of flight tickets. Other tools like, Google Flights, Skyscanner, and Kayak also allow you to compare prices across airlines. These tools often have price alert features, notifying you when fares drop for your selected routes.

Tip 4: Leverage Airline Sales and Loyalty Programs

Sign up for newsletters from airlines to get alert since airlines frequently announce flash sales or discounts on their websites and social media platforms. Additionally, enrolling in frequent flyer programs such as Delta SkyMiles or United MileagePlus lets you earn points for future discounts.
