Information about booking Fare Class OZ on Delta Air Lines.

Fare Class OZ is the lowest award fare class in the cabin. If you’re looking for flights and see Fare Class OZ 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.

In years past, searching for flights months out yielded OZ-fare class inventory because there were no customers booked in Delta One. Sometime in 2021-2022’ish, Revenue management blocked OZ-fare inventory for lowest fare sale until they explicitly released select inventory. This move effectively raised the cheapest fare for Delta One by controlling how many seats and when the seats this fare class is available for sale. Additionally, it eliminates savvy flyers seeking OZ fare class routes.

  • Searching for Fare Class OZ is nearly impossible through 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 OZ 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 OZ fare availability months in advance, which supports to theory of Revenue management controlling the release of these seats.
  • People who manage to book OZ 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 OZ fare bucket for sale.

Tickets purchased in Fare Class OZ will be the least expensive. To book a cheaper fare class, you’ll need to select a lower cabin or make the following changes (if you can):

  • Adjust your departure/return dates
  • Search for alternate airports or co-terminals
  • Search for alternate routing

  • It is unlikely to see buy up offers or MUAs because the ticketed fare class is the highest cabin of service available, but Delta's IT has been know to do shady, illogical things like sell you a buy-up to a refundable fare in the same cabin.
