Delta Airlines is gearing up for a very busy summer season in the domestic (United States) skies.
The Atlanta-based carrier on Friday announced a major route-map shakeup, adding multiple new routes and expanding services on many others focusing on domestic leisure travellers.
Expansion in services to the national parks
Delta is increasing service to nearly every major national park in the West, including on four routes to Bozeman, which is a major gateway to Yellowstone National Park. The airline is adding flights to Bozeman from New York-JFK, Los Angeles, Seattle and Detroit. Delta already serves Bozeman from its hubs in Atlanta, Minneapolis and Salt Lake City.

Delta growing its domestic leisure market
With long-haul international travel demand at some of its lowest levels in recent history, Delta Air Lines is busy using its idle planes to grow its domestic network.
This summer, Delta will offer more service to Montana than any other airline. At the same time, the carrier is bolstering its core hubs and giving some attention to its coastal hubs, where the recovery has been a little slower.
This recent growth comes after Delta announced expanded service to Alaska for the summer.
Every US airline is focusing on domestic routes
In the last month or so, IH Aviation and Travel has consistently been reporting about every airline in the United States announcing new destinations and routes and it looks like Delta is catching up with its rivals.
Alaska Airlines has announced 4 new routes out of Pacific Northwest for Summer 2021, Spirit Airlines has added 2 new destinations, Southwest has added flights to Montana and Florida and American Airlines has added a whopping 10 new routes from Austin.
Nevertheless, Delta is sticking to its longstanding hub-and-spoke strategy. The spokes are now just more outdoor-friendly cities. On the other hand, American and United have each experimented with point-to-point routes bypassing hubs.
Some of these new routes from Delta may only be around for a year or two. Once international long-haul flights come back, Delta will likely see some traffic to destinations like Jackson Hole or Savannah divert to destinations like Zurich or Cape Town. However, with international long-haul travel coming back slowly, and perhaps not until 2022 or 2023, the operator is likely to see some success on these domestic routes.
