2. Document everything: Screenshot app notifications, take photos of airport screens/boarding passes, record conversations (with permission where required).
3. Request assistance: Ask for meal vouchers, hotel stays, and transport if stranded overnight (mandatory under EU261/DOT for significant delays).
4. Rebook immediately: Choose the next available flight or alternatives; get written confirmation.
5. Gather receipts: For all out-of-pocket expenses (meals, hotels, transport).
6. Contact travel insurance: Notify if you have coverage.
7. File initial claim on-site/app: Start the process before leaving the airport.

Follow this, and you're positioned for refunds or compensation.
