Delta is aiming to deploy revenue management technology from Fetcherr across 20% of its domestic network by the end of 2025.
During its second quarter earnings call the airline's president Glen Hauenstein said the artificial intelligence pricing technology was currently being used for about 3% of the domestic network, up from 1% last November.
Fetcherr, a PhocusWire Hot 25 Travel Startup for 2023, has been working with Delta for more than 18 months.
The carrier said during its earnings call that it is still in the testing phase but is encouraged by the results.
Delta is in "heavy testing" according to Hauenstein.

"We like what we see. We like it a lot, and we're continuing to roll it out, but we're going to take our time and make sure that the rollout is successful as opposed to trying to rush it and risk that there are unwanted answers in there," he said.
The airline also said it is making "meaningful investments in technology" in other areas of the business including enhancing Delta Concierge, the virtual personal assistant that is part of the Fly Delta app.
Fetcherr announced $90 million in Series B funding in June 2024 and said it would fuel further growth and go towards recruitment.
The company, which was founded in 2019, also counts Virgin Atlantic, Royal Air Maroc and Viva Aerobus among its customers.
