If your United Airlines flight was delayed, canceled without enough notice, or you were bumped because of overbooking, you could be owed compensation.

Contact United Airlines directly for compensation

You can file a compensation claim directly with United Airlines through their customer relations form or email. However, you may experience:

• Multi-step paperwork that asks for receipts, boarding passes and baggage tags

• Dense legal language that can make it hard to tell what you’re really entitled to

• Automatic “no” notices, even when the airline clearly owes you money

• Lack of response or follow-up
