The airline does not respond to the complaint: what is the next step

If the airline asks for a supplement, check if the request is really incomplete or if it is asking for documents you have already sent. Sometimes the supplement is justified, and sometimes it is just part of a slow process.

Send what is reasonably missing and keep proof of sending. If you have already submitted the document, please respond calmly and re-attach it, noting when it was originally submitted.

The most common problem is the lack of a complaint reference number. Without it, it is more difficult to prove that the item exists and track the status through customer support.

Write down the flight date, complaint date, shipping channel, reference number, automatic confirmation date, each amendment and each reply. That simple chronology saves a lot of time later.

If a case is headed for a regulatory filing or legal review, a timeline is often the first thing to look for. It shows that you didn't just wait, you followed the procedure properly.

Add practical events to the timeline: when an alternative flight was offered, when you arrived, when you paid for your hotel or when you received a voucher.

Silence means that there is no real response after sending a complete complaint. An unreasonable response is when the airline sends a short message without specific facts, for example only extraordinary circumstances.

Both cases may require a next step, but the approach is not the same. With silence, the focus is on proof that you sent the request and that the deadline has passed. With a bad answer, the focus is on why the explanation is not sufficient.

So save the automatic replies as well. They can show that the airline has received the item, even if it doesn't match the content later.

If a reasonable amount of time has passed without a response, send a short follow-up. Enter the reference number, the date of the first request, the flight and briefly ask for the status or reasoned decision.

Do not send a new emotional complaint from the beginning. The goal of the follow-up is to show regularity and to leave a mark that you tried to resolve the matter directly with the carrier.

If the airline keeps asking for the same documents, respond with a list of what was attached and when. Such communication helps later if it is claimed that the documentation was not complete.

If the air carrier does not respond within the relevant time frame or the response does not contain a real explanation, the next step may be a regulatory complaint, a further formal warning or an assessment for the court route.

Do not escalate blindly. First, check that the basis of the request is realistic: the route, the reason for the disruption, the delay in arrival and the evidence. A weak case will not become strong just because the airline is late in responding.

If the foundation is good, neat documentation and a timeline give a much better position than a series of unrelated messages.

In such a case, it is useful to have someone read the entire communication and say what is missing: proof, deadline, legal basis, clearer request or next procedural step.

The goal is not to push every case at all costs, but to ensure that a good case is not lost due to poor procedure or the silence of the airline.

A review of the communication often reveals simple omissions: there is no reference number, no new itinerary is attached, the request mixes costs and compensation, or the airline's response is not saved in its entirety.

Once that's taken care of, the next step is much clearer. Sometimes a proper follow-up is enough, and sometimes it is better to immediately prepare the subject for further inspection.

If the demand is seen to be weak, this is also a beneficial outcome. Then you don't spend extra months on correspondence that can't change the basic facts.

If the request is good, an orderly package of evidence allows further steps to be taken more calmly and without constantly returning to the beginning.

Some airlines do not always send a clear email, but the status of the change remains in the portal or application. If you are waiting for a response, please also check the user account, spam folder, claim portal and all the addresses you used.

If you see the status closed, rejected or resolved without an explanation, take a screenshot. It's proof that the item exists and that the airline has made a decision, even if they haven't sent it to you properly.

In the follow-up, you ask that the decision and explanation be sent to you in writing. Without it, it is more difficult to understand whether to send a supplement, a complaint or a new request.

For the airline does not respond to the complaint: what is the next step, first check whether the route is protected, then what actually happened, and only then which claim makes sense. Use Air passenger rights for the baseline rule and amounts, while this page checks the concrete scenario and the evidence that changes it.

The best approach is to build a short timeline. Write down the scheduled time, actual time, where you were when the problem happened, what the airline offered, what you accepted and what you paid yourself. That timeline later decides whether the case is about fixed compensation, ticket refund, expense reimbursement or only care rights.

If the case involves arrival delay, a missed connection, rerouting or an overnight wait, also check flight delay compensation. Most practical passenger questions eventually depend on how late the whole journey ended and whether the reason was within the airline's control.

The strongest evidence is evidence from the same day: boarding pass, booking confirmation, airline messages, app screenshot, departures-board photo, receipts for food, hotel or transfer and any written information received at the airport.

If the reason was explained verbally, write down the exact wording, time and place. If the reason changed, keep every version. The difference between a technical fault, air traffic control, bad weather, strike and crew shortage is not a formality; it is often the line between a strong and weak claim.

In the claim, do not only say that you want compensation. Include flight number, date, route, booking reference, scheduled and actual arrival time, a short timeline and a clear separation between fixed compensation and expenses you want reimbursed.

The airline's first reply is often not a full assessment. It may contain broad wording, an automatically selected category or an answer that covers only one part of the claim. Read it carefully: does it address the exact flight, date, final destination and concrete reason that caused the disruption?

If the answer does not mention evidence, timeline or the measures the airline took, send a short follow-up. You do not need to repeat the whole story. Ask for a precise explanation and attach the most important proof again. That follow-up often separates genuinely weak cases from cases that were only rejected superficially.
