How to Book United Airlines Flights Online: Step-by-Step 2026 Guide
United Airlines gives travelers several ways to search and book. However, the online booking process through united.com offers the most competitive fares and the most control over your booking. Follow these steps to book United Airlines flights online in 2026.
Step-by-Step Booking Process
- Go to united.com and select your trip type, either round-trip or one-way.
- Enter your departure city, destination, and preferred travel dates in the search fields.
- Open the flexible date calendar to compare prices across a full month and spot the lowest available fare.
- Select your preferred cabin class from the available options.
- Review each fare type carefully: Basic Economy, Economy, Economy Plus, United Premium Plus, or United Polaris. Choose the fare that fits both your budget and your flexibility needs.
- For travelers aged 65 and older, select “Senior 65+” under the passenger type field. This step automatically applies available senior discounts on qualifying routes.
- Enter your passenger details exactly as they appear on your US passport or government-issued ID.
- Add your MileagePlus number to the booking. Note that Main Cabin and above earn miles normally, but Basic Economy earns zero miles from April 1, 2026 unless you hold a United co-branded credit card or Premier elite status.
- Select your seat, add checked baggage if needed, or include travel insurance at this step.
- Pay with a credit card, debit card, or MileagePlus award miles.
- Save your confirmation number and set a reminder for online check-in, which opens 24 hours before departure at united.com or through the United app.
| Pro Tip: United Airlines applies the US DOT 24-hour cancellation rule to all fare types. If you book at least seven days before departure, you can cancel within 24 hours for a full refund. This applies even to Basic Economy fares. |
Booking Channels for United Airlines
United Airlines passengers can book through multiple channels. First, united.com remains the primary channel and consistently offers the most competitive published fares. Second, the United Airlines mobile app provides mobile check-in, real-time flight updates, seat changes, and same-day standby requests. Third, phone booking is available directly through United Airlines, though online prices are generally more competitive. Additionally, a trusted travel agency like Ticket Business Class can access unpublished fares and provide up to 30% off United Airlines flights for US travelers. For the most current schedules and fare options, visit the official United Airlines website at www.united.com before you finalize your travel dates.
Buying a United Airlines ticket at an airport counter costs more than booking online. United Airlines does not offer lower prices at airport ticket desks. Travelers who book through united.com or a trusted travel agency access the most competitive fares available.

United Polaris Business Class and Premium Plus: Full 2026 Fare Breakdown
United Airlines changed its premium cabin booking approach significantly in April 2026. Specifically, the Chicago-based carrier introduced a new three-tier fare structure for both United Polaris business class and United Premium Plus on long-haul international, transcontinental, and select Hawaii routes. Understanding the difference between the three tiers saves you from expensive surprises at the airport.
Book United Airlines Flights in Polaris: Which Tier Should You Choose?
Polaris Base (the lowest Polaris fare) gives you the same lie-flat seat and identical onboard service as the higher tiers. However, United applies several meaningful restrictions to this fare:
- United charges extra for seat selection. You cannot choose your seat for free at booking.
- United limits Polaris Base passengers to one free checked bag instead of two.
- United grants access to the United Club lounge only. Polaris Base holders cannot enter the United Polaris Lounge.
- United does not permit ticket changes on Polaris Base fares.
- United blocks upgrades to Polaris Studio for Polaris Base holders.
- Additionally, Polaris Base fares earn reduced MileagePlus miles and no Premier qualifying flights toward elite status. However, passengers still earn Premier qualifying points.
Think of Polaris Base the way you think of Basic Economy in the economy cabin: United gives you the same seat and meals but removes several benefits you’d normally receive automatically with the ticket.
Polaris Standard restores the full business-class experience. United gives Standard fare holders two free checked bags, full United Polaris Lounge access with showers and sit-down dining in “The Dining Room,” complimentary seat selection, and some flexibility for ticket changes. Furthermore, Standard fare holders earn full MileagePlus miles on eligible bookings.
Polaris Flexible offers everything in Standard plus full refundability, maximum ticket change flexibility, and eligibility to upgrade to Polaris Studio. As a result, Flexible fares make the most sense for business travelers whose itineraries change frequently.
A real traveler scenario: A traveler from Houston recently booked a Polaris Base fare to London to save money upfront. However, United charged her extra for seat selection at the airport, limited her to one checked bag, and denied her Polaris Lounge access. As a result, she spent more than she originally saved compared to booking a Standard fare. That said, her onboard lie-flat seat experience was identical to every other Polaris passenger.
Polaris Studio: United’s Most Premium 2026 Product
You recline all the way into your Polaris lie-flat seat, pull the privacy divider closed, and reach for the Champagne. That’s what booking United Airlines Polaris Studio feels like in 2026. The Polaris Studio is United’s most premium seating product and carries a $499 per-segment surcharge above the base Polaris fare price. On a round-trip, that adds $998 in premium surcharges. Moreover, only Polaris Standard and Polaris Flexible fare holders can access Polaris Studio. Polaris Base fare holders cannot purchase the upgrade.
For US travelers who want the best value on lie-flat seats, you can Book United Airlines Business Class through Ticket Business Class and save up to 30% compared to booking directly on united.com.
United Premium Plus: Three Tiers in 2026
United Premium Plus offers premium economy seating on long-haul international and transcontinental routes. Passengers enjoy up to 7 inches more legroom and 3 more inches of recline compared to standard economy. In 2026, United now applies the same three-tier structure to Premium Plus: Base, Standard, and Flexible. Premium Plus Base limits passengers to one free checked bag and charges extra for seat selection. Additionally, Premium Plus Base does not allow ticket changes or upgrades. Standard and Flexible tiers restore the full premium economy experience.
Economy Fare Types on United Airlines
United Airlines offers three economy cabin options in 2026. Basic Economy provides the lowest price, but United assigns seats at check-in on domestic routes and does not include a carry-on bag for domestic travel. Most importantly, Basic Economy passengers earn zero MileagePlus miles from April 1, 2026 unless they carry a United co-branded credit card or hold Premier elite status. Economy is the standard economy fare and includes a carry-on bag and normal MileagePlus miles earning. Economy Plus adds up to 6 inches of extra legroom at the front of the economy cabin and free drinks on select flights.
Wi-Fi on United Airlines Flights
United Airlines provides Wi-Fi on most of its flights in 2026. Messaging is free for all passengers on most United flights. Surfing and streaming starts at $8 or 1,600 MileagePlus miles per flight. Furthermore, T-Mobile customers access free unlimited Wi-Fi on most domestic and international United flights, including streaming. Wi-Fi quality varies by aircraft and route, so travelers should check the coverage map on united.com before purchasing access.

- You cannot combine a senior fare with promotional codes.

Cheapest Days to Fly United Airlines in 2026
United Airlines flights typically cost less on Tuesday and Wednesday departures compared to weekends on many US routes. Specifically, flights departing Friday through Sunday carry higher prices due to peak leisure travel demand. The old “Tuesday price drop” idea came from airlines releasing fare sales on Tuesday mornings, with competing carriers matching those fares by Tuesday afternoon. However, United Airlines does not automatically drop prices on Tuesdays in 2026. As a result, targeting a single day of the week is less reliable than using united.com’s flexible date calendar to compare fares across an entire month.
Best time to book United Airlines flights in 2026:
- Domestic routes: book 3 to 8 weeks in advance for the best prices.
- International routes: book 3 to 6 months in advance.
- Cheapest months to fly: January and February, when leisure travel demand drops.
- Most expensive month: December, when holiday travel pushes average fares up to 12% higher.
- Off-peak months for savings: January, February, and September.
Money-Saving Tips for US Travelers Booking United Airlines Flights
United Airlines rewards travelers who plan ahead and use the right tools. Additionally, a few simple strategies consistently produce lower fares:
- Use the flexible date calendar on united.com to compare prices across the full month before picking a departure date.
- Join MileagePlus for free and add your number to every United booking to earn miles on eligible fares.
- Book round-trip tickets instead of two separate one-way tickets, since round-trips often offer lower combined fares on United routes.
- Fly through major United hubs like ORD, EWR, or DEN for more schedule options and sometimes lower connecting fares.
- Consider departing on Tuesday or Wednesday for potentially lower fares on many US routes.
- Book summer 2026 travel early, since demand is already high and prices climb as the travel season approaches.
