Types of Evidence Required for Flight Cancellation Claims

Gather these to prove booking, cancellation, and airline liability.

Digital Proofs: Screenshots, Emails, and Chat Logs

Screenshots of flight status apps (e.g., Flightradar24), emails from airlines, and chat logs are gold. They timestamp notifications--crucial if <14 days' notice.

Mini case study: A Paris-London flight cancelled via app chat (2025). Passenger's screenshots + PNR led to €250 EU261 win via Flightright.

Airline notification records prove lack of timely warning, boosting claims.

Official Records: PNR, Boarding Pass, and Flight Status

PNR is your booking's DNA (Lennuabi/AirHelp)--request it from airlines. Boarding passes confirm intent to fly, even if cancelled. Flight status screenshots verify cancellation timing.

Stats: PNR resolves 90% of disputes; vital for overbooking evidence.

COVID retroactive example: 2020 email + PNR secured refund in 2026--policies inconsistent but proof prevails (Autorite de la Concurrence).

Passenger Rights and Regulations: EU261 vs DOT vs Others (2026 Update)

EU flights emphasize compensation; US prioritizes refunds.

Regulation Coverage Compensation Refund Timeline Key Evidence
EU261 EU/UK flights, distance-based €250 (≤1,500km), €400/500 (1,500–3,500km), €600 (>3,500km); 50% reduction if re-routed timely 7 days (cash), 14 days COVID-era PNR, emails, boarding pass
DOT (US) US carriers/inbound No fixed comp; full refunds Automatic Ticket, notice
Montreal Convention Intl (136 states) Up to ~€1,500 SDR Varies Receipts, PNR

Force majeure: Weather yes, strikes no (EVZ.de). 2026 regs align timelines amid post-COVID recovery (32% seat recovery 2021).

Airline Liability and Extraordinary Circumstances: When Claims Succeed

Airlines liable unless "extraordinary" (burden on them).

Scenario Extraordinary? Evidence Needed Claim Success
Weather/Bird Strike Yes Status screenshots No comp
Overbooking No Boarding pass denial €250–€600
Staff Strike No (ECJ 2021) Airline chats Full claim
COVID Policies No (inconsistent) Emails/PNR Refund + comp

Mini case study: Overbooked Rome-NY (2024)--boarding pass + witness statement won €600. Bankruptcy? 78% chargeback success.

Force Majeure, Overbooking, and Bankruptcy Evidence

Pros/Cons Direct Claim Chargeback Legal
Speed Fast 45–90 days 6–12 months

Mini case study: EU261 win--PNR proved <14-day notice, €400 payout.

Claim Processes: Airline, Credit Card, Insurance, and Legal Routes

Direct: Fast, low success. Chargeback: 78% wins (any amount). Insurance: Needs PNR/emails. Legal: Higher payouts, fees.

US DOT Rules and Refund Evidence

Refunds for cancellations; evidence: ticket + notice. Federal Register: 96.6% large aircraft, easy digital proofs. Vs EU: No comp, but faster refunds.

Special Cases: COVID-19 Retroactive Claims, Bankruptcy, and More

COVID: Retroactive 2026 claims valid with emails/PNR--delays hit 14+ days (French-Property). 0.7% onboard transmission irrelevant.
