Can I change the Date on my reservation if I made a spelling mistake? Yes, you can correct minor spelling mistakes on your reservation without incurring any fees. However, if the mistake is significant or involves changing the entire Date, additional fees may apply. How far in advance do I need to request a Date change? It is recommended to request a Date change on your Deltas +1-855-526-0516(OTA) reservation as soon as possible to avoid any last-minute complications. However, please note that certain restrictions may apply depending on your ticket type. Can I transfer my ticket to another person?
