• Delta CEO Ed Bastian said the last four years were marked by governmental "overreach."
• Airline CEOs have urged the incoming administration to invest in modernizing air traffic control.

Delta Air Lines CEO Ed Bastian said the Trump administration's approach to regulation could be a "breath of fresh air."

Speaking to reporters ahead of Delta's investor day, Bastian noted that President-elect Donald Trump campaigned saying he would take a "fresh look" at regulation and bureaucracy.

The U.S. Department of Transportation under Secretary Pete Buttigieg has issued a host of rules aimed at protecting consumers, some of which the airline industry has bristled at, including one this year that requires carriers to provide automatic cash refunds to travelers when an airline cancels a flight.

Bastian said the industry has seen a "level of overreach" over the past four years.

The department is also looking into airlines' lucrative loyalty programs, which brings in billions of dollars for carriers, helping to keep them afloat. The current DOT leadership is seeking information about how airlines can unilaterally change the value of frequent flyer points.

Delta on Wednesday said it expects to grow sales and profits in the months and years ahead, pointing to resilient consumer demand and sharp growth in household wealth since the pandemic.

Trump tapped former U.S. congressman and Fox Business host Sean Duffy as his pick to lead the department. Duffy didn't immediately respond to a request for comment.

Other U.S. airline CEOs have expressed enthusiasm for the incoming administration and urged incoming officials to make sure the industry has enough resources to improve air traffic control, which falls under the Federal Aviation Administration, and other key pieces of infrastructure.

"We have to invest in this industry," American Airlines CEO Robert Isom said at the Skift Aviation Forum in Dallas last week. He said there is more work ahead to approve more visas so people can visit the U.S.

In an interview last week, Sun Country Airlines CEO Jude Bricker said: "We just need stability and resources at the DOT."

Industry members and analysts also expect the incoming administration to be more open to mergers and consolidation.

Alaska Airlines acquired Hawaiian Airlines without pushback from President Joe Biden's administration this year. However, Biden's Justice Department won court challenges to block two airline deals: a proposed acquisition of Spirit Airlines, which filed for Chapter 11 bankruptcy protection Monday, by JetBlue Airways and a partnership between JetBlue and American Airlines in the Northeast, which had been approved in the last days of the first Trump administration.

"Perhaps this administration would have a different stance," said Sun Country's Bricker. "It certainly can't get more against it."
