Any Delta Airlines flight leaving from an airport in Europe must abide by the European rule that safeguards travellers in the event of a delay. In accordance with EC 261, airlines are required to give delayed passengers access to food, drink, and communication devices. Additionally, they must provide lodging and alternative flights if necessary. You may also ask for a refund of your ticket in some circumstances, such as when your delta delayed flight compensation, especially if the substitute flight no longer serves your travel needs. Further, if Delta Airlines is at fault for the delay, they must reimburse passengers if the delay is 3 hours or longer, according to the legislation.
