Seven hubs, each with a job to do

United splits its flying across seven mainland hubs. Each one points in a different direction, and picking the right one can save hours on a connection.

Newark and Washington Dulles face Europe, San Francisco and Los Angeles face Asia and the Pacific, Houston looks south to Latin America, and Chicago and Denver stitch the country together.

Six tips for cheaper United fares

01

Price the bag, not just the fare

If you need a carry-on, standard Economy is often cheaper than Basic Economy plus a gate-check fee.

02

Try the other New York airport

United flies mostly from Newark. Compare it with fares into JFK and LaGuardia on the same dates.

03

Connect through Denver

For coast-to-coast trips a Denver or Chicago connection is frequently well below the nonstop price.

04

Book long-haul early

Transatlantic and transpacific fares are usually best two to six months ahead.

05

Use Star Alliance partners

Lufthansa, ANA, Air Canada and others can be combined with United on a single ticket.

06

Keep the 24-hour window in mind

Most U.S. bookings made a week or more before departure can be cancelled within 24 hours for a full refund.
