How Long Does Flight Compensation Take? Timeline by Airline and Method

"I submitted my EC261 claim weeks ago. When will I hear back?" It's one of the most common questions from passengers who've suffered a delayed or cancelled flight. The honest answer is: it depends — on which airline you flew with, how you submitted your claim, whether the airline disputes it, and whether you have to escalate.

This guide breaks down realistic timelines by method and airline, explains what causes delays, and tells you what to do if your claim is stalling. If you're not yet sure whether your flight qualifies, start with Your Complete EC261 Rights Guide.

The Short Answer

Method	Typical Timeline	Best-Case	Worst-Case
Direct claim (airline accepts)	4–8 weeks	7 days	6+ months
ADR / AviationADR (UK)	30–90 days after filing	3 weeks	6+ months
NEB complaint (national regulator)	Several months	6 weeks	1–2 years
Small claims court	4–8 months	3 months	2+ years
Claims management service	3–12 months (all-in)	6 weeks	3+ years

Note: "Best-case" assumes an uncontested claim. "Worst-case" typically involves an airline that contests at every stage.

Step-by-Step: What Happens When You Submit a Claim

Stage 1: Initial Airline Response

When you submit a compensation claim directly to an airline, EC261/2004 does not specify a mandatory response deadline. In practice, the European Commission's interpretative guidelines recommend that airlines reply within 2 months. Most industry experience suggests an initial response within 30 days — but this is only an acknowledgment, not necessarily a payment.

According to guidance from Bott and Co, "you should usually receive a response within 30 days, even if it is simply to say they are looking into the matter." (Source: Bott and Co EU261 Guide)

Stage 2: Payment If Accepted

If the airline accepts your claim, EU regulation requires them to pay within 7 days. Under Article 8 of EC261/2004, reimbursement and compensation must be provided within seven days. This applies once the airline has agreed to pay — not from the date you submitted the claim. (Source: EU261 Compensation Guide, Prince of Travel)

In practice:

• EasyJet users report payment within 7–8 days once confirmed, consistent with the regulatory requirement
• Ryanair has promised payment "within 10 working days" but users report delays beyond this in multiple documented cases (Source: Reddit /r/Flights)
• British Airways ADR cases are adjudicated with most decisions delivered within an average of 30 days once the ADR process starts

Stage 3: Rejection and Escalation

If the airline rejects your claim — or simply doesn't respond within 2 months — your options open up. For data on which airlines reject the most claims and which are most likely to require court proceedings, see our rejection rates guide. Stage 3 is where timelines diverge dramatically based on the method you choose.

Timeline by Method

Direct Claim to the Airline

Typical total time: 4–8 weeks for an accepted claim. Months to years if contested.

The direct claim route is fastest when the airline accepts your claim quickly. But airlines like Ryanair (74% of claims go to court proceedings), Vueling (84%), and Lufthansa (76%) routinely require escalation to resolve — meaning the direct claim is often just the first step in a longer process.

Key risks that delay direct claims:

• The airline doesn't respond within the recommended 2-month window
• The airline rejects citing "extraordinary circumstances" without specifics
• The airline offers a voucher instead of cash and waits to see if you accept
• Internal claims backlogs at the airline (some airlines process thousands of claims per day)

ADR (Alternative Dispute Resolution) — UK

Typical total time: 30–90 days from filing a complete case

Alternative Dispute Resolution is the fastest escalation route for most passengers in the UK. Approved ADR providers — AviationADR and CEDR — offer free adjudication for passengers; airlines pay the administrative costs.

AviationADR's published service commitment: "We are committed to managing claims within a 90-day timeframe upon receipt of requisite documentation from both the passenger and the airline. Nevertheless, most decisions are usually dispatched well before this deadline, falling impressively within an average span of 30 days." (Source: AviationADR)

The 90-day clock starts only once the Complete Complaint File (all documents from both sides) has been acknowledged — not from when you first file. Complex cases can exceed 90 days, with both parties notified of any extensions.

In the year to late 2024, AviationADR completed 44,783 cases, issuing 31,953 written determinations. ADR decisions are binding on the airline if you accept them.

Important: You must have completed the airline's internal complaints process before filing with ADR. Airlines must be registered with an ADR scheme to participate — all UK-licensed airlines are required to be.

National Enforcement Bodies (NEB)

Typical total time: Several months to over a year

NEBs are national regulators — in Ireland, the IAA (Irish Aviation Authority); in Spain, AESA; in the UK, the Civil Aviation Authority. Filing a complaint with an NEB is free, but NEBs investigate systemic issues rather than ordering payment in individual cases. You may not receive a direct financial outcome from an NEB complaint alone.

Ireland's IAA provides useful published benchmarks. In 2024, the IAA:

• Handled a total of 4,425 complaints (including backlog)
• Received 2,211 new complaints (a 30% decrease from 2023)
• Completed 3,669 investigations
• Upheld 47% of complaints in favour of the passenger
• Recovered €1,197,230 in passenger compensation and €360,104 in refunds

The most complained-about airlines in Ireland in 2024: Aer Lingus (33%), Ryanair (31%), Emerald Airlines (9%), Air France/KLM (3%), Lufthansa (2%). (Source: IAA Annual Report 2024)

NEB complaints are most useful as a parallel track while pursuing ADR, not as a primary resolution route.

Small Claims Court

Typical total time: 4–12 months for a hearing

UK small claims court is available for claims under £10,000 and allows passengers to represent themselves. Filing fees are low. However, if the airline contests the case — and airlines like Ryanair and Vueling have high litigation engagement rates — you may face a full hearing rather than early settlement.

British courts have established clear precedents favouring passengers. The case of Jet2.com Ltd v Huzar [2014] EWCA Civ 791 confirmed that a wiring defect in a fuel valve circuit was not an extraordinary circumstance, even though it was unforeseen — because it was intrinsic to the aircraft's operational system and thus within the airline's responsibility.

Claims Management Companies and Flight Compensation Services

Typical total time: 3 months to 3+ years, all-in

Claims management companies (CMCs) like AirHelp, Flightright, and law firms like Bott and Co handle the claim from start to finish on a no-win, no-fee basis. They typically charge 25–35% commission on any successful recovery (some charge additional administrative fees).

The appeal of using a CMC is leverage: companies with legal teams can file court proceedings efficiently, and airlines know this. Bott and Co's 2024 data shows that 46% of compensation claims across airlines require court proceedings — meaning a CMC is not just an administrative shortcut but sometimes the difference between getting paid at all.

The downside: timeline. Some CMC-handled claims, particularly those against airlines like Ryanair and Vueling that engage robustly in litigation, can take one to three years. One AirHelp user reported waiting a full year for a Ryanair EU261 delayed flight claim. (Source: Reddit /r/Ryanair)

For KLM: anecdotal reports include a claim that took three years to pay out. (Source: Reddit /r/KLM)

Airline-by-Airline: What to Expect

Ryanair

Ryanair has a high court-proceedings rate (74% of law firm claims). Direct claims may be promised in 10 working days but can extend. If rejected or ignored, ADR/NEB filing typically takes several months. Court route: highly variable, up to 1–2 years in contested cases.

Tip for Ryanair claims: Always follow up in writing with a reference to EC261 Article 7 and a specific 14-day deadline. Ryanair does settle claims — but usually only under legal or ADR pressure.

Wizz Air

Wizz Air has a 70% court-proceedings rate in Bott & Co data. Timeline for resolved claims is similar to Ryanair. Wizz Air paid £1.7 million via ADR in the year to October 2025 — suggesting escalation to ADR is effective.

EasyJet

EasyJet is reportedly one of the more difficult airlines for direct claims (known to offer vouchers, claim extraordinary circumstances incorrectly, and maintain backlogs). However, once a claim is accepted, the 7-day payment window is generally honoured. ADR escalation typically resolves within the standard 30–90 day window.

British Airways

BA has a relatively good payment rate once claims reach ADR (83% uphold rate). Most ADR decisions are dispatched within approximately 30 days. Direct claim response: typically within 30 days.

Note: BA adjudicators have found the airline did not "sufficiently demonstrate" that defects were unforeseeable — in one case finding that the defect was known since 2017. If BA cites extraordinary circumstances, challenge this specifically.

Lufthansa

Lufthansa's official guidance states that if you have contacted Lufthansa and have not received a reply within two months, or are dissatisfied with the outcome, you may escalate to an ADR body. (Source: Lufthansa Passenger Rights) The 76% court-proceedings rate suggests many claims require escalation beyond the initial 2-month window.

KLM

KLM claims are variable. Some are paid within 2–4 weeks; others have reportedly taken three years. (Source: Reddit /r/KLM) File in writing and track response dates carefully.

TAP Air Portugal

TAP has a history of refusing payment by citing extraordinary circumstances. CJEU case C-74/19 arose directly from TAP refusing to pay compensation on grounds of extraordinary circumstances — a refusal that was challenged and taken to court. (Source: CJEU, Case C-74/19) Allow 2–4 months for a direct claim; NEB escalation in Portugal or Spain is available.

Air France

Air France claims follow the standard EU pattern: 2-month recommended response window, ADR escalation available if unsatisfied. No airline-specific quantitative timeline data is available for Air France beyond general EC261 benchmarks.

What Causes Payment Delays?

1. "Extraordinary Circumstances" Disputes

The most common cause of delayed payment is an airline invoking extraordinary circumstances to reject a claim. When passengers dispute this — through ADR or court — the resolution process takes months rather than weeks. Airlines know the defence is often weak (technical faults are not extraordinary circumstances under CJEU case law), but deploying it buys time.

2. Missing Documentation

ADR bodies require a Complete Complaint File from both the passenger and the airline before the clock starts. If you don't submit your original booking confirmation, boarding pass, and delay certificate, the clock doesn't start. Airlines can also slow-walk their own documentation submission.

3. High Claim Volumes

Summer disruptions generate claim surges. Airlines processing thousands of claims per day inevitably have longer queues. The CAA ADR data shows that 43,238 complaints passed through ADR in a single year — a substantial processing burden.

4. Incorrect Claim Submission

Claims submitted without the flight number, date, route, and specific grounds for compensation are delayed or rejected outright. Always include: full flight details, the specific disruption (delay duration, cancellation notice period), and the EC261 provision you are relying on.

Practical Tips to Speed Up Your Claim

Start with a proper written claim. Email is better than web forms — it creates a timestamped paper trail. Include: flight number, date, route, disruption type, your contact details and bank details for payment.

Set a calendar reminder for 30 days and 2 months. If you haven't received a substantive response within 30 days, send a chase. If no satisfactory resolution by 2 months, escalate immediately to ADR.

Don't accept a voucher. Accepting a travel voucher may complicate or forfeit your right to the cash compensation you're owed. Write back clearly rejecting any voucher offer and requesting cash payment.

File with ADR before the window closes. In the UK, ADR claims must generally be filed within 12 months of the airline's final decision. Don't wait.

Use FlightOwed to check your claim. Our free eligibility check tells you in two minutes whether your flight qualifies for EC261 compensation and what you're owed.

Consider a claims service for high-resistance airlines. If you're claiming against Vueling, Ryanair, or Lufthansa and don't want to spend months on correspondence, a claims management service's legal leverage often resolves things faster than individual escalation — even after accounting for their commission.

Frequently Asked Questions

How long does an airline legally have to respond to an EC261 claim?

EC261/2004 does not set a mandatory response deadline. The European Commission's interpretative guidelines recommend airlines reply within 2 months. If you don't receive a satisfactory response within that window, you can escalate to an ADR body or NEB without waiting further.

If an airline accepts my claim, how quickly must they pay?

Once compensation is approved, payment must be made within 7 days under EC261 Article 8. In practice, some airlines take slightly longer, but payment within 7–14 days is the norm after acceptance.

Is using an ADR provider faster than going to court?

Significantly faster for most claims. AviationADR (UK) targets a 90-day resolution from filing the complete case, with most decisions delivered within 30 days on average. Small claims court typically takes 4–8 months for a hearing, and contested cases can extend considerably longer.

Can I claim for a flight that happened 2 or 3 years ago?

Yes, in many cases. Time limits vary: UK allows up to 6 years, Germany 3 years, France 5 years. Retroactive claims are entirely valid — see our full guide on retroactive claims and time limits, or check your flight at FlightOwed to see if yours still qualifies.
