My issue is with Delta Vacations. Much like the Expedia and agency issues I just read, I booked 5 tickets for my entire family to travel to the U.K. My mother's name is Patricia Dianne Johnson and that is how I booked the ticket. On her passport, she used her previous last name and it reads Dianne Nelson Johnson. Delta airlines says they cannot change because it was booked through Delta Vacations. Delta Vacations will not change and insists that we need to cancel her ticket and rebook for more than $2000. What can I do? I am the one who made the mistake and everything else matches. I just realized the issue as I was gathering our travel documents and saw her passport for the first time. The address, birthday, and even the credit card that purchased the tickets all match.
