Delta launches new routes from Boston to NYC shortly after JetBlue's withdrawal.

Delta Air Lines is swiftly aiming to take over some of the market space JetBlue Airways has vacated.

The Atlanta-based airline submitted plans over the weekend for two exciting new routes, one departing from Boston and the other from New York, as reported by Cirium Diio schedules.

Initially, Delta will introduce daily flights between Boston Logan International Airport (BOS) and San Antonio International Airport (SAT), starting on Nov. 11. This route will run year-round and will be the sole nonstop service between Boston and San Antonio.

Worth considering: Are airline credit cards still a good deal?

Delta will introduce a 109-seat Airbus A220-100 on this route, featuring 12 first-class recliners, 15 Comfort+ extra-legroom seats, and 82 standard economy seats. The A220 offers a delightful flying experience with its large windows, spacious overhead bins, and a comfortable 2-3 seating arrangement.

The flight will take off from Boston at 9:15 a.m. and arrive in San Antonio at 1:13 p.m. It will leave SAT at 2 p.m. and return to Boston by 7:05 p.m.

In a recent announcement, Delta stated that "adding the Boston-San Antonio route to our network will offer the only nonstop flights between these two cities beginning in November. This service will enhance Delta's presence in the top 50 markets from our Boston hub and reinforce Delta's leading position there."

In addition, the airline will commence flights between John F. Kennedy International Airport (JFK) and Palm Springs International Airport (PSP) starting December 21. This weekly service, which will run on Saturdays, will utilize the larger Airbus A220-300, featuring 130 seats: 12 first-class recliners, 30 Comfort+ extra-legroom seats, and 88 standard economy seats.

It boasts several passenger-friendly features similar to those found on the smaller A220-100 variant, including the window in the lavatory.

Delta aims to offer the JFK-to-PSP route seasonally until May 3, 2025, with the potential to extend the season or add more flights during the week if the route proves popular.

These new flights will depart New York at 8:45 a.m., arriving in Palm Springs at 10:50 a.m. The return flight will leave at 12:50 p.m., landing back in New York at 8:35 p.m.

Although these two routes are new for Delta, there's an interesting twist: JetBlue Airways — one of Delta's major competitors in Boston and New York — recently withdrew from both markets a few weeks ago.

In its quest for profitability, JetBlue, the New York-based airline, has been reducing its network to lower capacity. The airline recently announced its decision to withdraw from seven additional cities, including Palm Springs and San Antonio.

JetBlue's BOS-to-SAT route will conclude on October 26, and the airline will not be resuming its JFK-to-PSP service as part of its winter schedule.

For years, Delta and JetBlue have been vying for supremacy in two of the Northeast's largest markets, and it appears Delta is quickly capitalizing on JetBlue's exit.

It will be intriguing to observe the future of these routes, particularly the Palm Springs service, which JetBlue previously operated daily during peak winter times. Delta's weekly flights will certainly attract some warm-weather travelers, but they may not suit those looking to fly on days other than Saturday.
