Insider Booking Tips: How to Find Cheap United Airlines Flights
Finding affordable airfare on United Airlines doesn’t have to be a mystery. Here are some proven strategies for scoring cheap United Airlines flights:
Book in Advance
Prices tend to rise significantly as the departure date approaches. Booking 6–12 weeks ahead can often result in the best fares.
Use Flexible Date Searches
Use tools like Google Flights or United’s own flexible date search to find the cheapest days to fly. Mid-week flights (Tuesdays and Wednesdays) are generally less expensive.
Monitor Fare Alerts
Set up fare alerts on platforms like Skyscanner, Hopper, or Kayak to get notified when prices drop for your preferred route.
Leverage the MileagePlus Program
Use or earn miles through United’s loyalty program. You can redeem miles for free flights, upgrades, or perks. United also offers co-branded credit cards to accelerate your mileage accumulation.
Avoid Peak Travel Seasons
Traveling during off-peak times—such as late January, early spring, or post-summer—can yield cheaper fares and less crowded airports.
Check Partner Airlines
Thanks to Star Alliance partnerships, booking through partner airlines like Air Canada, Turkish Airlines, or ANA might show different pricing for the same route.
Try Alternate Airports
Look at nearby airports for better deals. For example, flying out of Newark instead of JFK, or into Gatwick instead of Heathrow, could save you money.
Book One-Way Flights Separately
Sometimes, two one-way tickets are cheaper than a round-trip ticket—especially when combining different carriers or booking via different platforms.
Use Points + Cash Options
If you’re short on miles, United’s Points + Cash feature allows you to offset the cost of your flight with a partial redemption.
