Delta announced three domestic routes on Friday, including two from its hub at Los Angeles International Airport.
Starting Dec. 19, the carrier will offer twice-daily service between Los Angeles and Monterey, California. Flights will be operated by Delta Connection using Embraer E175 aircraft.
The carrier last served Monterey in 2008, according to Cirium Diio schedule data.
A mainline connection linking Los Angeles and Philadelphia will come online June 7, 2027, for the summer travel season. Flights will operate daily using Airbus A321neos.
Also on Dec. 19 of this year, Delta will start daily service between Salt Lake City and Monterey.
“We’re continuing to invest in more ways for customers to experience everything California has to offer,” Amy Martin, vice president of network planning at Delta, said in a news release. “With new service to Monterey from both Los Angeles and Salt Lake City, alongside our continued growth at LAX, we’re creating more opportunities for customers to connect to the places they want to go while building on our long-term commitment to Los Angeles and the West.”
The carrier will also add frequencies on several existing routes from Los Angeles. Service from Los Angeles to Boston will increase to five times daily; Raleigh-Durham, North Carolina, to twice daily; San Diego to five times daily; Seattle to eight times daily; Houston to three times daily; Cincinnati, Ohio, to twice daily; and San Antonio to three times daily.
