How to complain to an airline in the UK about bad service (with a sample letter)
Maybe staff were unhelpful, information was unclear, or you were left waiting with no real support. Whatever happened with your flight, it’s reasonable to expect better.
If an airline’s service falls below standard, you are entitled to complain. And when you do it properly, you stand a much better chance of getting a clear response instead of a generic apology or worse, no reply at all.
This guide explains how to complain to an airline, what to include in your message, as well as a sample airline complaint letter you can use as a starting point.
When should you complain to an airline in the UK?
You don’t need a dramatic incident to justify a complaint. Many everyday situations are worth addressing with the airline. Some of the most common issues that passengers have include:
- Airline staff being rude, dismissive, or unhelpful
- Poor communication during delays or disruptions
- Long waits at the airport with no updates or assistance
- Being left without food, water, or basic care
- Problems with compensation for delayed, damaged, or lost baggage
- Issues with seating, accessibility, or special assistance
- Being sent from desk to desk without answers
- Poor in-flight experience
If the airline’s service made your journey more difficult than it needed to be, it’s worth raising a formal complaint.
What to do before making an airline complaint
You don’t need to prepare a legal case, but a little organisation and attention to detail helps. So, before you prepare your letter, gather the following:
- Your boarding pass and booking confirmation
- Any communication you had with the airline about the issue
- Photos if they back up your case
- Emails, texts, or app notifications from the airline
Clear details make it easier for the airline’s customer service team to understand what went wrong and respond properly.
How to complain to an airline in the UK
Most airlines ask passengers to submit complaints through their website, usually via a customer service or feedback form. Some airlines also accept complaints by email or post.
Always use the airline’s official complaints process where possible. This helps ensure your complaint is logged and gives you a reference number for follow-up.
Also, you don’t need to use strong language or legal wording. In fact, those often work against you. A better approach is to be clear, calm, polite, but also firm and factual.
Think of it as explaining the situation to someone who wasn’t there and needs the full picture.

What happens after you complain to an airline?
UK airlines often take a few weeks to respond, especially during busy travel periods. Keep a copy of your complaint and any replies you receive.
If you don’t hear back:
- Follow up using your complaint reference number
- Check whether the airline offers an escalation or alternative dispute option
- Stay polite but persistent
It’s reasonable to expect a clear response once your complaint has been reviewed.
Remember, you’re not being difficult by raising your concerns and disappointment about your flight. By complaining, you’re asking for accountability when service falls short of what you’d expected from your flight.
If your flight was delayed, canceled or overbooked within the last 3 years, you could be eligible for up to £520 in compensation.Check Your Flight
