Even the best and most highly regarded airlines can fall short from time to time, and when they do, it’s fair to file a complaint. Not only will it resolve the issue on your end, but it will also help carriers like Thai Airlines to improve their services.

To help you understand the complaint process, we’ll be going through the following:

• What you can complain about that will lead to compensation
• Your rights as a Thai Airways passenger
• The steps you should take to submit a complaint
• How to contact Thai Airways

If your flight was delayed, canceled or overbooked within the last 3 years, you could be eligible for up to €600 in compensationCheck Your Flight

Typical Thai Airways Complaints

From seat comfort to slow boarding process, passengers complain about so many different things, but not all of them will result in a compensation payout. Below are some of the most common issues people have. They also happen to be the ones most likely to get you something for your trouble.

• Flight delays: When Thai Airways flights are delayed, you could get a maximum of £520 (€600) as long as your trip meets certain criteria.
• Flight Cancellations: As well, flights cancelled by Thai Airways with less than 2 weeks notice get you compensation similar to that of delays.
• Denied boarding: As a ticketed passenger, if you’re bumped because your flight was overbooked, you could be entitled to £520 (€600) in compensation.
• Lost or damaged baggage: If Thai Airways loses or damages your luggage you could claim as much as £1,300 (€1,700).
• Poor Customer Service: Did something in-flight or otherwise not meet your expectations? File a complaint so the airline can improve. They might just give you vouchers or discounts to make it right.

Thai Airways Complaints: Helpful Tips

To make sure your complaint is addressed properly, here are some things to remember:

1. Timing is everything. The longer you wait to submit your complaint with Malaysia Airways, the less likely you are to remember the details necessary to get compensation.
2. Make sure to keep your booking details and travel documents. Things like your boarding pass, baggage tags, any correspondence, and anything else you can think of can be included in your complaint, and it will help your chances of a payout.
3. Provide as many details as possible about your experience. The more specifics you include, the stronger your claim will be.
4. State your expected resolution. In your mind, you’ve already decided what you need to be satisfied, so always be clear about your desired outcome.

Always send your issue to the airline ASAP.

What Are Your Thai Airways Passenger Rights?

Anytime your Thai Airways flight leaves from an airport in the European Union or the United Kingdom, you’ll be protected by the air passenger rights from these locations, which happens to be some of the best in the world!

Regulation EU261 in Europe and Regulation UK261 for the UK both describe the rules that all airlines must follow if they fly out of these areas. As a passenger, this means that you could be owed £520 (€600) in compensation depending on the distance of your flight and the length of your delay at the final stop.
