If you need to complain to Expedia, you can follow a few simple steps to make sure your concern is heard. First, call their customer service directly at 1-877-827-8493. This is a quick way to reach a representative who can listen to your issue and help you with a resolution. Be sure to have your booking details ready, including your itinerary number, email address, and travel dates, so the agent can locate your file easily.

When calling, clearly explain the nature of your complaint. Whether it's about a booking error, a flight cancellation, hotel issues, refund delays, or poor service, stay calm and provide specific details. If the first representative cannot resolve your problem, you can ask to speak with a supervisor or escalate the issue within the call.

In addition to calling, you can file a written complaint through your Expedia account. Log in, go to your itinerary, and select the booking in question. Look for the option to contact support or file a complaint. Include relevant screenshots, receipts, or communication history to support your case. Providing clear documentation can strengthen your complaint and lead to a quicker resolution.

If you don’t get a timely response, follow up through the same number or try using Expedia’s social media channels, where companies often respond faster to public posts. Make sure to remain polite but assertive. Always keep records of your conversations, names of agents, and reference numbers for future reference. If the issue remains unresolved after several attempts, you can explore filing a formal dispute with your bank (if it involves a refund), or consider seeking outside mediation through consumer complaint platforms.

Remaining persistent, respectful, and well-documented is key to getting results when complaining to Expedia.
