Many tickets allow for standard flight adjustments, such as date, time, and destination, up to 24 hours before the flight's departure. If you want to modify the ticket within 24 hours of the flight leaving, there are different rules. After the risk-free cancellation period, some tickets, such as Basic Economic fares, cannot be changed. The passengers included in that specific reservation will all be subject to any adjustments made in accordance with Delta Airlines' change flight policy. All Delta tickets purchased for travel departing from North America to any location in the world, barring Basic Economic prices, are now free of change and award redeposit costs.
