A booking inventory alone doesn't tell you anything, since most of them are used for more than one type of fare. The truly distinguishing code on your ticket which tells the airline all the rules of your ticket, is the "Fare Basis Code" which is a series of letters and / or numbers, usually no more than 1-12 digits long, and is generally found in the upper middle of your ticket.
Booking code 99-9997 is typically a generic code used by airlines to represent a general/held reservation without specific details. It does not provide any specific information about the flight or booking details. It is usually used for reference purposes or to indicate a placeholder.
I assume you mean "Airline Code". If so, it is DL.
