How to complain to an airline after a delay or cancellation
A good request is not long. A good request is specific: flight, date, route, what happened, what you are looking for and evidence to support it.

Start with facts, not emotions
Complaints to the airline should be clear and verifiable. Before sending, prepare the flight number, date, departure airport, arrival airport, booking reference and a short description of the disturbance.
If you had a connection, please provide the final destination from the entire reservation, not just the segment that was delayed. With a missed connection, it is often how late you were at the last airport that matters, not just how late the first flight was.
It is not necessary to write a long emotional description. The airline needs enough information to find the flight, understand the basis of the claim and see what evidence you are providing.
- flight number and date
- route and final destination
- booking reference or ticket number
- planned and actual arrival time
Clearly separate what you are looking for
If you are asking for a fixed fee due to delay, cancellation or denied boarding, write it directly. If you are asking for a ticket refund, hotel or meal reimbursement, put it as a separate line item.
Mixing refunds, vouchers, airport care and fixed compensation often creates confusion. Support then only answers the easiest part, for example the ticket refund, and ignores the fee.
It is better to write three short requests than one long message asking everything at once. This makes it easier to prove later what you were really looking for.
Attach the evidence in a neat package
Attach the reservation confirmation, boarding pass or check-in confirmation, airline messages and proof of actual arrival with the complaint. If you are asking for expenses, please attach receipts.
If you don't have all the documents, send what you have and clearly write what is missing. Missing one document doesn't have to mean the end, but it's better to be transparent than to send a vague request.
Give the evidence an understandable name: ticket, boarding-pass, cancellation-message, hotel-receipt. It seems small, but it reduces errors in manual processing.
Use the official channel
Most airlines have a web form or portal for complaints. If there is an official channel, use it first. After sending, save the confirmation, screenshot and reference number.
If you are sending an email, save the sent message and the automatic reply. Without proof of sending and receiving, it is later more difficult to claim that the complaint was filed on time.
Do not send the same request to ten addresses on the same day. This usually does not speed up the subject, it creates confusion. It is better to have a clear request, then a proper follow-up if there is no answer.
Follow the deadlines and response
After sending, make a short note: date of complaint, channel, reference number and what you have attached. If the airline asks for a refill, note when you sent it.
If a reply arrives, don't just look at whether it says accepted or rejected. Check the reason. Denial due to extraordinary circumstances, weather, air traffic control or technical problem should be specific enough to be verifiable.
If there is no response within the relevant time frame or the response is generic, the next step may be a further warning, regulatory filing or legal assessment. Before escalation, however, check whether the basis of the request is realistic.
When it makes sense to ask for help
If the case is clean, you can try it yourself. If there is a connection, redirection, rejection, unclear reason or communication in multiple languages, help can save time.
Before or after the complaint, letkasni.rs can check whether the case makes sense, what is missing and how to avoid losing the request due to bad procedures.
Help is especially useful when you receive a partial response: for example, part of the ticket was refunded, but the fixed fee was not answered, or the hotel costs were acknowledged, but the reason for the delay was not explained. Then you need to know what is still open.
If you are submitting the request yourself, please save all receipts. If you turn on the service later, proper prior communication allows for a faster assessment and fewer repetitions of the same questions.
This is especially important with family and group bookings, where one slip in documentation can slow down all passengers.
Expect the process to take some time
Serious services openly state that simple cases can be resolved quickly, but disputed cases can take months, especially if the airline refuses, asks for amendments or the case goes to a regulator or court.
That's why it's important to keep a neat folder from the start. If after three months you need to refill the item, you don't want to search for the boarding pass through old messages or remember who said what at the gate.
A good claim is not just one message. It is a process: sending, confirming receipt, following the deadline, replying, supplementing, eventual escalation and deciding whether to continue.
