Common questions
Questions travellers ask us.
What is ComplainAI?
ComplainAI is an AI-powered travel complaint letter generator. Describe what went wrong — a delayed flight, lost baggage, an unfair hotel or car-rental charge — and it writes a formal demand letter citing the exact passenger-protection law that applies, such as Canada's APPR, the EU's EU261, US DOT rules, or the Montreal Convention. Generating and reading your letter is free; you pay only to download or send it.
How much compensation can I claim for a delayed flight?
It depends on where you flew. Under Canada's Air Passenger Protection Regulations (APPR), large airlines owe up to $1,000 CAD for long arrival delays within their control. Under EU261, qualifying flights can pay up to €600 per passenger. Your letter states the exact amount for your specific delay and route.
How much does ComplainAI cost?
Generating and reading your full letter is free. You only pay to download or send it — from US$3 for a single letter, with unlimited plans up to US$25 per year.
Does ComplainAI work in both Canada and the US?
Yes. ComplainAI covers Canadian flights under the APPR, US flights under Department of Transportation rules, EU and UK flights under EU261 and UK261, and international baggage claims under the Montreal Convention — plus hotels, car rentals, cruises, and booking platforms.
How is ComplainAI different from AirHelp or other claim companies?
Claim companies typically take a percentage of your compensation as commission. ComplainAI charges a flat fee starting at US$3, you keep 100% of whatever you recover, and you stay in control — you send the letter yourself and the company pays you directly.
Is this legal advice?
No — ComplainAI is a letter-writing tool, not a law firm. It drafts complaint letters based on published consumer-protection and passenger-rights laws, but it does not provide legal advice.
