United Airlines Contact Info

Beyond checking to see the status of your United Airlines flight, you might need to contact them to file a complaint for delays, canceled flights, or baggage mishandling. 

Anytime you have issues with an airline, you should always try to address the problem as soon as it happens, and ideally while you’re still at the airport. Understandably, this might not always be possible, in which case you’ll need to contact United in other ways to lodge a complaint. If you want to file a United compensation claim, you’ll have to do so in writing, but more on that later.

United Airlines Customer Service

Calling United usually involves waiting for some time on hold until you can speak to a live person. So, if you want to avoid the hassle of phoning the airline, you can try to reach them through other means.

If you want to avoid the trouble of filing a compensation claim on your own, you can let the experts at AIrAdvisor handle the claims process for you!

What to do if United’s customer service doesn't respond?

Most airlines are flooded with complaints and compensation claims, and United is no exception. Because of this, they might take a very long time to respond, or they might not do so at all.

If this happens to you, remember that AirAdvisor can take the necessary steps to get compensation for you. This means we will submit your compensation form and provide all the relevant details about your flight disturbance, and then follow up with the airline, even if that means taking them to court.

Step-by-step instructions for a complaint with UnitedAirlines

For a successful claim, you’ll need to submit as much detailed documentation as possible including the following:

1. Personal information: Your full name, contact information, and address. Make sure this information matches what you provided when you purchased your ticket(s).
2. Flight details: Add the details of your flight disruptions, including the flight number, date, as well as departure and arrival airport.
3. Type of interruption: Describe what happened - whether you had a delay, cancellation, denied boarding, or a missed connection.
4. Details about your flight disruption: If your flight was delayed or canceled, provide the scheduled departure/arrival times as well as the actual departure/arrival time. If your flight was canceled, then  include the reason given to you by airline staff.
5. Information on denied boarding: If you were denied boarding, say whether it was a voluntary or involuntary denial and indicate the reason given to you by the airline.
6. Additional costs: If you incurred expenses as a result of the delay, include this information as well, along with any receipts. This is important because you may be able to get reimbursed for these.
