Questions, answered

No. ComplainAI drafts formal complaint letters citing public travel regulations — it is a writing tool, not a law firm. For complex disputes, consult a lawyer.
It uses your departure country, arrival country, and the carrier's country of registration to determine which regulations apply. A Canadian flight departing the UK triggers UK261. An EU carrier arriving in Canada triggers both EU261 and APPR. The determination is made before the letter is written — you can see exactly which laws will be cited before paying.
It's a formal demand letter addressed to the airline or operator's complaints department. It states the facts, cites the specific article of the applicable regulation, names the compensation amount you're owed, sets a reply deadline, and states which regulator you'll escalate to if ignored. You can see a full example at the link below.
Every letter sets a response deadline. If it passes, we generate a follow-up escalation addressed directly to the relevant regulator — the CTA in Canada, US DOT in the United States, or your provincial/state consumer office.
No. You read the full letter before paying anything. Payment unlocks the PDF download, copy-to-clipboard, and response tracking.
Yes — for trips departing or arriving in Canada, the United States, the EU, and the UK. The system picks the laws that match your specific route and carrier.
