Delta Fare Class Z

Delta Fare class Z is a revenue fare/booking class of service that is marketed as Discount First Class / Delta One on Delta Air Lines. The fare class is considered a discounted First Class / Delta One.

Below is a human-readable explanation of this fare class and the expectations passengers should have when flying with a Z fare class.

How expensive is Fare Class Z?

Fare Class Z is marketed as a discount first class / Delta One ticket, and is the lowest revenue fare class in the cabin. If you’re looking for flights and see Fare Class Z showing as the lowest fare class available, it means the cabin for the flight/route you are booking is nearly empty with only few seats booked on one or more segments of the itinerary.

Tickets purchased in Fare Class Z will be the least expensive. Booking this fare class will be challenging:

• Searching for Fare Class Z is nearly impossible through Delta.com and they have deprecated the advanced search feature which used to allow passengers to search by Fare Class.
• It is advised to call into reservations and get a knowledgeable ticketing agent to search your destination for Fare Class Z availability. Unfortunately, getting a knowledgeable ticket agent is very hard post-COVID as the newer agents have not been trained on DL Term or any other system than their point-and-click reservations system. You will have to hang up and call again (HUCA).
• Many frequent flyers are reporting no Z fare availability months in advance, which supports to theory of Revenue management controlling the release of these seats.
• People who manage to book Z fares have reported that the fare class came available a few weeks to month out. The theory behind this is that the Delta One seat sales were lagging behind the forecasted load and thus Revenue Management released a seat or two into the Z fare bucket for sale.
• It is large reported that Delta Vacations has access to the Z fare bucket to hide the cost of a flight into their overpriced “packaged deal”.
