Delta Airlines Flight Name Change Policy
Things to Consider Before Making Name Corrections with Delta Air
Passengers can change the surname shown on the ticket in the event of marriage or divorce. To do this, you must also present the relevant documents.
Additionally, passengers can correct any spelling errors on the ticket at any time, free of charge.
If you have entered your nickname in the form by mistake, you can change it and present it along with your photo ID upon check-in at the airport.
Visitors cannot change the last name from Sr. to Jr. or vice versa.
The most important thing is that you cannot transfer your ticket to another passenger.
