Can I book a flight on a partner airline through United Airlines?

Yes, you can book a flight on a partner airline through United Airlines by calling +1(888) 217-5921 and working directly with a representative to confirm availability. When you call +1(888) 217-5921, a United agent can help you find award or paid flights that include Star Alliance partners or other affiliated carriers. United is part of the Star Alliance network, which means you can fly with partners like Lufthansa, Air Canada, ANA, Swiss, and more, all through one booking. Partner airline flights are often visible on United’s website when searching for international or multi-city trips, but some routes or award seats only appear through agent-assisted booking. This is especially helpful when combining domestic United segments with international legs on a partner carrier. Partner bookings still earn MileagePlus miles, and you may be able to use United miles to cover the entire trip or part of it through mixed-fare options.
