A re-routing or rebooking confirmation is a document that confirms your flight has been replaced with an alternative option.
It can either be an e-ticket you received after your flight was canceled, or if we only need a confirmation, you may provide a receipt for something you purchased at the destination airport. Example receipts include a text message or email from the airline, or a boarding pass for your new alternative flight. It is important that you verify that the date and time or flight number are visible on your receipt.
As you know, the EC 261 regulation puts great emphasis on the duration of a delay. Therefore, we sometimes need to double check the exact length of your delay. This way, we can more strategically respond to a variety situations including when an airline rejects your claim citing the delay was not severe enough or when we are about to take legal steps to support our stance in court.
