Airline information

Flying United Airlines: what to know

Cabins & classes

United Airlines operates the standard long-haul cabin tiers found on most major carriers: economy, premium economy (on wide-body routes), business, and first (on select flagship services). For the exact cabin layout of your specific flight, the fare detail at checkout shows seat map and amenity info. For a primer on what each class actually includes, see our premium cabin guide.

Baggage & carry-on

Carry-on and checked baggage allowances depend on your fare class and itinerary. Basic economy fares on most US carriers are the most restrictive; premium cabins usually include two checked bags of higher weight. The specifics for your ticket appear in your Aviafares confirmation email. Our baggage policy guide covers typical limits and fees across carriers.

Check-in & boarding

Online check-in typically opens 24 hours before departure on United Airlines's own website or app using your booking reference (PNR) and last name. Arrive at the airport 90 minutes before a domestic flight and 2-3 hours before an international flight. Priority boarding is included with premium cabin fares and tier status.

Fare rules & changes

Refund and change rules are set per fare class by the airline. The US Department of Transportation requires a full refund for any US-touching flight cancellation on any fare. For voluntary changes, our agents can handle the rebook at the airline's published fees. See our fare rules primer and refund policy.

Frequent flyer & miles

Tickets issued through Aviafares are standard revenue tickets. You earn United Airlines miles (and partner- program credit where applicable) at the same rate as booking on the airline's own site. Add your frequent-flyer number at checkout, or email us after booking to have it added to the PNR.

Booking support

Changes, cancellations, or irregular-operations rebooks on your United Airlines ticket can be handled directly by our booking team: call 24/7 or request a callback. For detail on how we handle each scenario, see booking support.
