How do I get a refund from United Airlines? Fill out the refund form if you've already canceled your reservation, and They'll get back to you as soon as possible to let you know if your ticket qualifies for a refund. Your refund will be credited to your original form of payment if your ticket qualifies. It might take 7 business days for your refund request to get processed. Refunds for tickets purchased in overseas locations may arrive at a different time.
