"We've grown 60 percent over the past five years" in number of seats sold on flights to and from Salt Lake City, he said. "That's a very large number. There's no reason to think we can't continue to grow and expand here."
He adds, "It's a great destination market. And as we rebuild the airport here, there's going to be even more opportunities down the road" for enhanced operations.
Bastian became CEO of Delta in May after 18 years with the company — including quitting once over dissatisfaction with the direction it was taking, only to be brought back later to help restructure it.
He's no stranger to Salt Lake City. He owns a condo in Deer Valley. While he loves to ski there, he says he actually prefers coming during the summer to explore and enjoy the mountains.
Bastian says he wants Utahns to view Delta as their hometown airline.
"In 2015, we finished with almost 15 million passengers carried to and through Salt Lake," he said. "It's a very important market for us."
He said recent efforts to build international partnerships may bring more international flights here.
For example, he said Salt Lake City benefited from Delta buying a 49 percent interest in Virgin Atlantic. "We would not be flying today from Salt Lake City directly to Heathrow [in London] had it not been for that" and "the customers they brought us."
Similarly, he said Delta is finalizing a deal to buy a 49 percent stake in Aeromexico. "That should close by the end of this year. We're going to create a joint venture, so I think you are going to see more traffic go through" Salt Lake City to Latin America.
He said other partnerships could also help expand service to Mexico and Canada. Bastian said present service from Salt Lake City to Europe — in London, Amsterdam and Paris — could also expand over time, but probably not immediately.
"We just launched London and Amsterdam within the last year, so we need to get those markets matured," he said. "The first year is always a build year. Depending on how those markets mature, there could be additional opportunities for expansion."
He expects additional growth to domestic locations from Salt Lake City. "We're going to be launching [nonstop flights to] Miami in December. We just started Raleigh-Durham," and he adds he sees more opportunities coming.
Bastian said Delta also has been replacing small regional planes with "mainstream" larger planes, and more of that will be seen with a new 110-seat plane to be introduced here soon — which he says should enhance customer experience.
