    Yes, it doesn't apply to tickets purchased over the phone, through a travel agent or via any other ticketing channel.

  • What is the “booking class” and how do I find this information on my Delta ticket?

    The booking class designates the type of fare you purchased and the cabin in which you purchased a seat. It will begin with a letter such as U, T, L, K, etc. and will usually be the first letter of the “Fare Code” or “Fare Basis Code.” An example of a booking class may be (L) and the fare basis code may be “LE7NR”. On the Delta ticket, you will find your booking class under the header “Flight and Cabin (Class)” and is located in the Trip Summary section after selecting your flights or under the “Fare Rules” section. Other websites may have this information under “Fare Rules and Restrictions” or “Fare Terms and Conditions” and can be located on the website prior to purchasing your ticket.
