How to Find Cheap United Flights

Everyone wants a good deal. These simple tricks can help you save money on your next United flight.

Be Flexible with Your Travel Dates

Prices change depending on demand. Midweek flights are usually cheaper than weekends. Use the flexible date search tool to view fares over a few days or a whole month.

Book Early

For domestic flights, book at least 2–3 weeks in advance. For international trips or peak travel times, try to book 6–8 weeks ahead. The earlier you book, the better your chances of getting a lower fare.

Use Fare Alerts

Sign up for United’s email offers or enable alerts on the mobile app. You’ll get notifications when prices drop or when sales are active.

Redeem Miles

If you’re a MileagePlus member, you can use your miles to book free or discounted flights. Miles can also cover upgrades, luggage, or in-flight extras.

Check for Promotions

Look out for seasonal deals, flash sales, or partner offers. You may find discounts when booking hotels, car rentals, or vacation packages with your flight.

Compare Before Booking

Use flight comparison tools like Google Flights or Skyscanner to see how United’s prices stack up. Then book directly on the United website for the best support and fare conditions.

What to Do If You Miss a United Airlines Flight

Life happens. If you miss your flight, don’t panic. United Airlines Missed Flight has steps in place to help you get back on track.

United’s Flat-Tire Rule

If you’re late due to things out of your control—like traffic, weather, or a flat tyre—United may rebook you on the next flight without charging a change fee. This is not a guaranteed policy, but staff at the airport may apply it if you arrive within two hours of your original flight.

Same-Day Standby

If you miss your scheduled flight, you may be eligible for same-day standby. This means you can wait for the next available flight on the same day. There might be a small fee, and seats are not guaranteed.

No-Show Policy

If you don’t show up and don’t inform United, your full itinerary could be cancelled. This includes return and connecting flights. Always notify United if you’re going to miss a flight so you don’t lose the rest of your trip.

Rebooking Options

If your flight is missed, you can:

• Rebook through the United website or app
• Visit a service desk at the airport
• Call United customer service

You may need to pay a fare difference or change fee, depending on your ticket type.

Other Helpful Tips for United Travellers

Download the Mobile App

The United app lets you check in, track flight status, get boarding passes, and change bookings on the go. It also sends gate change and delay alerts.

Check In Online

You can check in up to 24 hours before your flight. This saves time at the airport and lets you pick your seat.

Arrive Early

Arrive at the airport at least 2 hours before domestic flights and 3 hours before international flights. Allow time for check-in, baggage drop, and security screening.

Keep Documents Ready

Bring valid ID or passport. For international flights, check for visa requirements in advance.
