Does Treader file my flight compensation claim for me?

No. Treader checks what the rules pay and drafts the letter; you send it to the airline yourself, and Treader takes no cut of what it pays.

How much compensation do I get for a delayed flight in Canada?

Under APPR, a large airline pays $400 CAD for a 3 to 6 hour arrival delay, $700 for 6 to 9 hours and $1,000 for 9 or more; a small airline pays $125, $250 and $500. It applies when the cause was in the airline's control and not for safety.

How long does an airline have to answer a compensation claim?

Under APPR, 30 days, and you can ask until a year after the flight. Under US DOT rules, 60 days. EU261 sets no deadline, so the letter asks for six weeks.

Can I check what my flight pays without a Discovery plan?

Yes. The free checker at treader.ca/flight-delay-compensation needs no account and covers delays, cancellations and bumping, but not bags.

Draft a flight delay compensation claim

A delayed, cancelled or bumped flight, or a lost bag, can be worth money under rules set by the route, not by how nicely you ask. The claim builder in Travel Data, part of Discovery at $9.99 CAD a month or $99.99 a year, checks what Canada's APPR, the EU's 261/2004 or the US DOT rules pay and drafts the letter with its citations. You send it yourself: Treader files nothing, takes no cut, and gives guidance, not legal advice. For what to do at the gate first, read When your flight goes wrong.

What it covers

The 3 rule sets cover delays, cancellations, denied boarding and lost or damaged bags; UK rules are not covered. APPR pays cash for a delay or cancellation only when the cause was within the airline's control and not for safety, and you were told 14 days or less before departure. The amounts, last checked in August 2026:

Delay or cancellation. From a 3-hour arrival delay, $400 to $1,000 CAD under APPR on a large airline and $125 to $500 on a small one, or 250 to 600 euros by distance under EU261. US DOT pays no cash, only a refund if you decline the rebooking after a cancellation or a big schedule change.
Denied boarding. Up to $2,400 CAD under APPR, 250 to 600 euros by distance under EU261, or 200% or 400% of your one-way fare under US DOT, capped at $2,150 USD.
Lost or damaged bags. Proven costs up to 1,519 SDR (about $2,900 CAD plus bag fees under APPR, about 1,800 euros under EU261), or up to $4,700 USD on a US domestic trip. Keep every receipt.

The rules themselves

How to build a claim

On a flight stop in your trip, tap Check status. When the flight shows 3 hours late or cancelled, Discovery adds Start a claim, which opens a claim with the flight, date and disruption filled in and the rules picked from the route.

1 In Travel Data, go to Claims and press New claim. It starts on Canada (APPR).
2 Set Rules that apply, Disruption and the facts each asks for, such as whether the cause was in the airline's control.
3 Enter the flight. A flight already in your vault is flagged as a match, not copied into the form.
4 Read Estimated compensation: the amount, the section it rests on, and your band in the rate table.
5 Pick a Tone and press Generate claim email. Tone changes the greeting, opening, deadline and sign-off, never the legal basis. With Scout vault access on, Refine with Scout offers a revision that lands only when you press Use this.
6 Copy the letter or Export PDF, send it through the airline's own claim form or email, and tap Mark sent to start the response clock: 30 days under APPR, 60 under US DOT, and 6 weeks under EU261, which sets no deadline of its own.
7 If the airline stalls, Escalated to CTA (under APPR) only records the step; the complaint itself goes through File a complaint with the CTA under Read the law.

Facts in, an assessed amount out, then the letter.

Tip

Regenerate email replaces the whole letter, including anything you typed and any Scout text you kept, and a new tone or a corrected fact only reaches the letter through it. Set the tone and the facts first, then edit by hand. The rest of the paperwork is a stage of the trip planning checklist.
