How to Get Cheap Flight Tickets
Finding cheap flight tickets saves money for both business travel and vacations. This guide covers when to book, how to compare prices, which airlines and tools to use, and how to set price alerts so you can book at the right time.
Book at the right time
Timing matters. For domestic US routes, booking one to three months ahead often yields better prices than last-minute or very early booking. For international trips, two to four months ahead is a common sweet spot. Use our Best Time to Book Flights guide for seasonal and route-specific tips. Pair this with Track Flight Prices so you get alerts when fares drop.
Compare multiple search tools
No single site has the lowest price every time. Use Google Flights for quick US and international comparisons and flexible date grids. Use Skyscanner to see a wider set of online travel agencies and “whole month” views. Check airline sites directly for flash sales and member-only fares. For a head-to-head, see our Google Flights vs Skyscanner comparison.
Be flexible on dates and airports
Flying midweek (Tuesday or Wednesday) is often cheaper than weekends. Red-eye and early-morning flights can be less expensive. If you have multiple airports nearby, compare all of them—sometimes a short drive to a different airport saves a lot. Use the Salary Calculator to weigh job opportunities in cities with cheaper or better-connected airports when planning relocation or remote work.
Consider budget airlines
Low-cost carriers like Spirit, Frontier, and Allegiant offer lower base fares on many US routes. Total cost depends on baggage, seats, and add-ons—factor those in before you book. For an overview of who flies where and how they compare, see our Cheapest Airlines in the USA guide. Use our Personal Finance Planner to set a travel budget so you know how much you can spend on flights and still hit your savings goals.
Set price alerts and book when it makes sense
Google Flights and Skyscanner let you set price alerts for specific routes and dates. When you get an alert, compare the price to what you’ve seen before and book if it fits your budget. Avoid waiting forever for a “perfect” price—once you’re in a good range, booking locks in the fare and lets you plan the rest of your trip.
