Know Before You Claim. The pre-claim decision system that names the regime, estimates the band, and writes the letter.

The Flight Compensation Eligibility Checker is the complete build-to-launch blueprint for a decision-tree calculator and claim kit — a regime selector across UK261, EU261, US DOT refund rules and the Montreal Convention, a six-stage eligibility tree, a compensation calculator that never says “you qualify”, an extraordinary-circumstances challenge module, nine claim letters, an escalation router, and the pricing, SEO and revenue model to sell it.
Route, operating carrier, disruption type, arrival timing, notice given, cause, booking type, elapsed time. Get one wrong and the answer changes completely.
Every regulatory statement in this blueprint is labelled Verified regulatory rule, Product interpretation, Marketing assumption or Example calculation — with the source and date for each. Nothing is stated as settled law that isn't.
Everything needed to answer one question for a stranger in ninety seconds: where do I actually stand, and what do I send?
Five questions that decide which of UK261, EU261, US DOT rules or the Montreal Convention apply — and it returns more than one where more than one is true.
Journey, disruption, timing, cause, responsibility, booking type. Every question the user sees belongs to exactly one stage.
Verified bands for every regime, returned as a claim category with its conditions attached — never as a figure the user is told they are owed.
Thirteen stated causes, how each is generally treated, and the nine-question Airline Explanation Challenge the customer can send unaltered.
A dedicated splitter that keeps the three entitlements apart on every screen, so a customer never abandons two because the airline answered one.
Who to claim from, what goes in which letter, and the disclosure paragraph that keeps both claims credible under the no-double-recovery rule.
Delay, cancellation, denied boarding, refund, expenses, package, rejection response, extraordinary-circumstances challenge and final demand — written in full.
A personalised “what am I missing?” list, and a six-rung ladder that names the specific ADR scheme, enforcement body or authority for that flight.
Pricing ladder, SEO cluster, 11 free lead-gen calculators, sales page, ad angles, 7-email funnel, revenue model at four scale points, and the MVP roadmap.
Handling claims for clients who cannot face the airline themselves.
Needing sourced rules, not blog summaries.
Preparing files that survive an ADR submission.
Turning post-trip disruption into a service line.
Building free calculators around high-intent search.
Wanting an authority page instead of another listicle.
Answering the same nine questions every disruption season.
Needing a defensible information/advice boundary.
The blueprint specifies this screen line by line, including the confidence model and the words the product is never allowed to use.
Departure and destination country, operating carrier, single booking or two, passenger count — distance is computed, never asked.
Delay, cancellation, denied boarding, missed connection or downgrade — and they are not mutually exclusive.
Arrival delay at the final destination, and for a cancellation the exact date and time notice was received.
A structured cause list, including a prominent option for “the airline said extraordinary circumstances without specifying”.
Within, outside, or entirely fact-dependent — with the exact evidence to request in each case.
Flight-only or package — one addressee or two, and a second letter set where both routes are live.
UK claims route through approved ADR schemes or the CAA's advisory team. EU claims route through the relevant National Enforcement Body. US claims route through the Department of Transportation. The blueprint refuses to assume every dispute follows one path.
Through the carrier's own claims channel, with every passenger named and the three entitlements separated.
Answering the specific reason given, not re-arguing the whole claim.
In the UK, a decision by a CAA-approved scheme binds the airline.
The relevant NEB in the EU, the CAA's advisory route in the UK, the DOT complaint process in the US.
With the correspondence trail the blueprint's tracker has already assembled.
With the seven signals that tell you a claim has outgrown a self-service tool.

Regime selection, cause classification, evidence, letters, response analysis and marketing — every one carrying an anti-fabrication constraint.
Full text with merge fields marked, plus the tone rules enforced at template level.
Journey facts, timing, cause, the three-claim split, evidence audit, deadlines, package split and escalation plan.
Date, action, who contacted, response, claimed, offered, next step and deadline — with eleven status options and a worked example.
UK261, EU261, US DOT and Montreal side by side across nine dimensions (Appendix A).
Twenty primary sources, named, so every rule in the book can be checked (Appendix C).
Twenty items on a monthly, quarterly, annual and on-event cadence — including the three live watch items as at August 2026.
Day-numbered, from building the rule packs to publishing the first review dates.
Ten questions, one screen at a time, no account needed. A named regime instead of a guess. Their refund, their compensation and their expenses kept as three separate claims instead of one. A personalised list of the four documents they are missing rather than nineteen they might need. A letter they can send today. And when the airline replies “extraordinary circumstances”, nine specific questions to send back — because that is a determination, not a full stop.
The promise is deliberately narrow and deliberately honest: know whether you may have a claim, understand what it could be worth, and know exactly what to do next — before you give up a percentage of your compensation, or give up on the claim entirely.

This is a blueprint for building a product, not a live tool. If your flight is disrupted today, go to your national aviation authority's own guidance first.
Claims management is a regulated activity in some jurisdictions. The blueprint sets the boundary clearly — it does not qualify anyone to cross it.
A complete written blueprint — the passenger playbook, the decision-tree logic, the calculator specification, the letters, the results-page copy, the commercial model and the roadmap. It is not source code and it is not a live application.
No. It is educational and informational, and the product it specifies is designed to say so on every result screen and in every generated document.
Every regulatory figure was verified against a named primary source — the UK Civil Aviation Authority, EUR-Lex, the eCFR and Federal Register, and ICAO — and reviewed on 24 August 2026. Appendix C names all twenty sources so you can check them yourself.
That is designed for. Every rule lives in a versioned data file with its own review date, so a change is an edit rather than a rebuild. The book names three live watch items as at August 2026, including an EU reform that is agreed but not yet in force.
Yes, and it is explicit about the most important difference: US rules require refunds in defined circumstances but do not mandate cash compensation for delays or cancellations. Chapter 5 covers the automatic refund rule, the significant-change thresholds, denied-boarding compensation and the complaint route.
They are labelled planning assumptions, not forecasts, and the label appears before the first table. The product does not exist yet, so there is no performance data — and the chapter says so.
Possibly, but claims management is regulated in some jurisdictions and marketing that implies legal services can breach professional-title rules. Chapter 48 sets out the boundary and what must never be claimed.
