Tips for finding cheap United flights
United domestic fares tend to be most competitive 3 to 6 weeks before departure. For international routes, booking 2 to 4 months ahead usually finds the best prices.
United's Basic Economy is the lowest fare but restricts seat selection and doesn't allow changes. It's only a good option if you're certain of your travel dates and are packing light.
Tuesdays and Wednesdays consistently show the cheapest fares on United's domestic network. Avoid Friday and Sunday, which peak with business and leisure demand.
United's MileagePlus partners with over 40 Star Alliance carriers. If you have miles, premium routes on Lufthansa, Singapore Airlines, or ANA can be excellent value redemptions.
