This year just got started, but it is already shaping up nicely for U.S. airlines.

After several setbacks, the industry ended 2024 in a fairly strong position because of healthy demand for tickets and the ability of several airlines to control costs and raise fares, experts said. Barring any big problems, airlines — especially the largest ones — should enjoy a great year, analysts said.

“I think it’s going to be pretty blue skies,” said Tom Fitzgerald, an airline industry analyst for the investment bank TD Cowen.

In recent weeks, many major airlines upgraded forecasts for the all-important last three months of the year. And on Friday, Delta Air Lines said it collected more than $15.5 billion in revenue in the fourth quarter of 2024, a record.

“As we move into 2025, we expect strong demand for travel to continue,” Delta’s chief executive, Ed Bastian, said in a statement. That put the airline on track to “deliver the best financial year in Delta’s 100-year history,” he said.

The airline also beat analysts’ profit estimates and said it expected earnings per share, a measure of profitability, to rise more than 10 percent this year.

Delta’s upbeat report offers a preview of what are expected to be similarly rosy updates from other carriers that will report earnings in the next few weeks. That should come as welcome news to an industry that has been stifled by various challenges even as demand for travel has rocketed back after the pandemic.

“For the last five years, it’s felt like every bird in the sky was a black swan,” said Ravi Shanker, an analyst focused on airlines at Morgan Stanley. “But it appears that this industry does have its ducks in a row.”

That is, of course, if everything goes according to plan, which it rarely does. Geopolitics, terrorist attacks, air safety problems and, perhaps most important, an economic downturn could tank demand for travel. Rising costs, particularly for jet fuel, could erode profits. Or the industry could face problems like a supply chain disruption that limits availability of new planes or makes it harder to repair older ones.

Early last year, a panel blew off a Boeing 737 Max during an Alaska Airlines flight, resurfacing concerns about the safety of the manufacturer’s planes, which are used on most flights operated by U.S. airlines, according to Cirium, an aviation data firm.

The incident forced Boeing to slow production and delay deliveries of jets. That disrupted the plans of some airlines that had hoped to carry more passengers. And there was little airlines could do to adjust because the world’s largest jet manufacturer, Airbus, didn’t have the capacity to pick up the slack — both it and Boeing have long order backlogs. In addition, some Airbus planes were afflicted by an engine problem that has forced carriers to pull the jets out of service for inspections.

There was other tumult, too. Spirit Airlines filed for bankruptcy. A brief technology outage wreaked havoc on many airlines, disrupting travel and resulting in thousands of canceled flights in the heart of the busy summer season. And during the summer, smaller airlines flooded popular domestic routes with seats, squeezing profits during what is normally the most lucrative time of year.

But the industry’s financial position started improving when airlines reduced the number of flights and seats. While that was bad for travelers, it lifted fares and profits for airlines.

“You’re in a demand-over-supply imbalance, which gives the industry pricing power,” said Andrew Didora, an analyst at the Bank of America.

At the same time, airlines have been trying to improve their businesses. American Airlines overhauled a sales strategy that had frustrated corporate customers, helping it win back some travelers. Southwest Airlines made changes aimed at lowering costs and increasing profits after a push by the hedge fund Elliott Management. And JetBlue Airways unveiled a strategy with similar aims, after a less contentious battle with the investor Carl C. Icahn.

Those improvements and industry trends, along with the stabilization of fuel, labor and other costs, have created the conditions for what could be a banner 2025. “All of this is the best setup we’ve had in decades,” Mr. Shanker said.

That won’t materialize right away, though. Travel demand tends to be subdued in the winter. But business trips pick up somewhat, driven by events like this week’s Consumer Electronics Show in Las Vegas.

The positive outlook for 2025 is probably strongest for the largest U.S. airlines — Delta, United and American. All three are well positioned to take advantage of buoyant trends, including steadily rebounding business travel and customers who are eager to spend more on better seats and international flights.

But some smaller airlines may do well, too. JetBlue, Alaska Airlines and others have been adding more premium seats, which should help lift profits.

While he is optimistic overall, Mr. Shanker acknowledged that the industry was vulnerable to a host of potential problems.

“I mean, this time last year you were talking about doors falling off planes,” he said. “So who knows what might happen.”

The lobby of Shutters on the Beach, the luxury oceanfront hotel in Santa Monica that is usually abuzz with tourists and entertainment professionals, had by Thursday transformed into a refuge for Los Angeles residents displaced by the raging wildfires that have ripped through thousands of acres and leveled entire neighborhoods to ash.

In the middle of one table sat something that has probably never been in the lobby of Shutters before: a portable plastic goldfish tank. “It’s my daughter’s,” said Kevin Fossee, 48. Mr. Fossee and his wife, Olivia Barth, 45, had evacuated to the hotel on Tuesday evening shortly after the fire in the Los Angeles Pacific Palisades area flared up near their home in Malibu.

Suddenly, an evacuation alert came in. Every phone in the lobby wailed at once, scaring young children who began to cry inconsolably. People put away their phones a second later when they realized it was a false alarm.

Similar scenes have been unfolding across other Los Angeles hotels as the fires spread and the number of people under evacuation orders soars above 100,000. IHG, which includes the Intercontinental, Regent and Holiday Inn chains, said 19 of its hotels across the Los Angeles and Pasadena areas were accommodating evacuees.

The Palisades fire, which has been raging since Tuesday and has become the most destructive in the history of Los Angeles, struck neighborhoods filled with mansions owned by the wealthy, as well as the homes of middle-class families who have owned them for generations. Now they all need places to stay.

Many evacuees turned to a Palisades WhatsApp group that in just a few days has grown from a few hundred to over 1,000 members. Photos, news, tips on where to evacuate, hotel discount codes and pet policies were being posted with increasing rapidity as the fires spread.

At the midcentury modern Beverly Hilton hotel, which looms over the lawns and gardens of Beverly Hills, seven miles and a world away from the ash-strewed Pacific Palisades, parking ran out on Wednesday as evacuees piled in. Guests had to park in another lot a mile south and take a shuttle back.

In the lobby of the hotel, which regularly hosts glamorous events like the recent Golden Globe Awards, guests in workout clothes wrestled with children, pets and hastily packed roll-aboards.

Many of the guests were already familiar with each other from their neighborhoods, and there was a resigned intimacy as they traded stories. “You can tell right away if someone is a fire evacuee by whether they are wearing sweats or have a dog with them,” said Sasha Young, 34, a photographer. “Everyone I’ve spoken with says the same thing: We didn’t take enough.”

The Hotel June, a boutique hotel with a 1950s hipster vibe a mile north of Los Angeles International Airport, was offering evacuees rooms for $125 per night.

“We were heading home to the Palisades from the airport when we found out about the evacuations,” said Julia Morandi, 73, a retired science educator who lives in the Palisades Highlands neighborhood. “When we checked in, they could see we were stressed, so the manager gave us drinks tickets and told us, ‘We take care of our neighbors.’”

Hotels are also assisting tourists caught up in the chaos, helping them make arrangements to fly home (as of Friday, the airport was operating normally) and waiving cancellation fees. A spokeswoman for Shutters said its guests included domestic and international tourists, but on Thursday, few could be spotted among the displaced Angelenos. The heated outdoor pool that overlooks the ocean and is usually surrounded by sunbathers was completely deserted because of the dangerous air quality.

“I think I’m one of the only tourists here,” said Pavel Francouz, 34, a hockey scout who came to Los Angeles from the Czech Republic for a meeting on Tuesday before the fires ignited.

“It’s weird to be a tourist,” he said, describing the eerily empty beaches and the hotel lobby packed with crying children, families, dogs and suitcases. “I can’t imagine what it would feel like to be these people,” he said, adding, “I’m ready to go home.”
