When personal circumstances or changes in travel plans arise, customers occasionally want to modify their airline bookings. You don't need to worry if you fly with Delta Airlines because the airline believes in giving its clients and passengers complete flexibility when it comes to making modifications to their travel tickets. A passenger must have a complete understanding of the Delta flight change policy and its terms & conditions before using the airline's flight change service. To learn more about the specifics of the Delta change flight policy, see the section below. Customers can easily take advantage of Delta's same-day flight change options. According to this guideline, a traveller is changing their itinerary less than 24 hours before the original departure time. Only travellers flying between the US Virgin Islands or Puerto Rico and the US are covered by this policy.
