GLENDALE (AP) — A consumer class action lawsuit filed Tuesday claims Delta Air Lines inaccurately billed itself as the world’s “first carbon-neutral airline” and should pay damages. The complaint in federal court in California alleges the airline relied on carbon offsets that were largely bogus.

Companies around the world buy carbon credits to cancel out their carbon releases with projects that promise to absorb carbon dioxide out of the air, or prevent pollution that would’ve happened. But they’ve been under the spotlight in recent months with claims their benefits are exaggerated.

The company is a big customer, purchasing credits from projects including wind and solar projects in India and an Indonesian swamp forest, the lawsuit says.

Delta spokesperson Grant Myatt described the lawsuit as “without legal merit.”

“Since March 31, 2022, (Delta) has fully transitioned its focus away from carbon offsets toward decarbonization of our operations, focusing our efforts on investing in sustainable aviation fuel,” Myatt said in an email. He added that the company is renewing its fleet with “more fuel-efficient aircraft and implementing operational efficiencies.”

The case, filed by Glendale, California resident Mayanna Berrin, claims to act on behalf of anyone who flew Delta while living in the state since March 2020. It says benefits from the offsets are likely to be temporary and would have happened even without the firm’s investment. For a carbon credit to be valid, it must provide a benefit that would not have happened otherwise.

Delta announced three years ago it would go carbon neutral, which means releasing no more climate-changing pollution into the air than it absorbs. It can also mean paying to guarantee it is absorbed elsewhere.

Berrin argues this enabled the firm to gain market share and charge higher prices. A writer for Nickelodeon, Berrin told The Associated Press she is about to enter her thirties and climate anxiety is pronounced in people her age.

“I felt comfortable paying more because I was neutralizing when I needed to travel for work or to see my family,” she said. She said she felt frustration and regret when she began having doubts about Delta’s offsets.

“They can’t just claim neutrality if that’s not factually accurate,” she said. “Lawsuits in general are very scary, and there are a lot of people who echo my frustrations who may not know their rights or the impact they can make by speaking up.”

Her attorney Jonathan Haderlein believes it’s the first such case against a major American airline, and one of just a handful of “greenwashing” cases in the U.S. based on consumer protection law.

The case number is 2:23-cv-04150.

In 2021 aviation made up more than 2% of global CO2 emissions, according to the International Energy Agency.

DALLAS (AP) — The unofficial start of the summer travel season is here, with airlines hoping to avoid the chaos of last year and travelers scrounging for ways to save a few bucks on pricey airfares and hotel rooms.

Some travelers say they will settle for fewer trips than they hoped to take, or they will drive instead of fly. Others are finding different money-saving sacrifices.

Stephanie Hanrahan thought she’d save money by planning ahead for her daughter’s birthday trip to Disney World in Florida. Instead, it ended up costing the same as the Dallas-area family’s trip for four to California last summer, so now her husband and son are staying home.

“We just had to grit our teeth,” said Hanrahan, a writer and speaker who also runs a nonprofit, as she and daughter Campbell waited for their flight last week at Dallas Love Field.

The number of people going through U.S. airports hit pandemic-era highs last weekend, and those records are almost certain to be broken over the Memorial Day holiday.

AAA predicts that 37 million Americans will drive at least 50 miles (80 kilometers) from home this weekend, an increase of more than 2 million from Memorial Day last year but still below pre-pandemic numbers in 2019. The Transportation Security Administration expects to screen 10 million travelers between Friday and Monday, a 14% increase over the holiday in 2022 and slightly more than in 2019.

With more travel comes more expense. The average rate for a U.S. hotel room last week was $157 a night, up from $150 in the same week last year, according to hotel data provider STR. And the average daily rate for other short-term rentals such as Airbnb and Vrbo rose to $316 last month, up 1.4% from a year ago, according to AirDNA, which tracks the industry.

There is a bit of good news for drivers, however: The national average for a gallon of regular was $3.56 at midweek, down from $4.60 at this time last year, according to AAA. Renting a car is also cheaper than a year ago, when some popular destinations ran out of vehicles. Travel company Expedia said larger inventories let the companies rent more cars at lower prices.

For air travelers, airline industry officials say carriers have fixed problems that contributed to a surge in flight cancellations and delays last summer, when 52,000 flights were nixed from June through August. Airlines have hired about 30,000 workers since then, including thousands of pilots, and they are using bigger planes to reduce flights but not the number of seats.

“I don’t have the hubris to tell you exactly how the summer is going to go, but we have prepared and we have a robust plan for it,” said Andrew Watterson, chief operating officer at Southwest Airline, which struggled at times over the summer of 2022 and suffered an epic meltdown around Christmas, canceling nearly 17,000 flights.

David Seymour, the chief operating officer of American Airlines, said his staff has fine-tuned a system it uses to predict the impact of storms on major airports and devise a plan for recovering from disruptions. He said it is reducing cancellations.

“It’s going to be a solid summer for us,” Seymour said.

In a report released last month, the Government Accountability Office blamed airlines for an increase in flight cancellations as travel recovered from the pandemic. It also said airlines are taking longer to recover from disruptions such as storms.

Transportation Secretary Pete Buttigieg says the government will hold airlines responsible to treat passengers fairly when the carriers cause cancellations or long delays. But just like the airlines, the Federal Aviation Administration — the agency that manages the nation’s air traffic — has had its own staffing shortages and occasional technology breakdowns that have snarled air travel.

The FAA resorted to nudging airlines to reduce flights in the New York City area this summer, and it opened new flight paths over the East Coast to reduce bottlenecks.

“It’s going to be an ordeal — it’s always an ordeal to travel in the summer,” said travel analyst Henry Harteveldt, “but the airlines have done a lot to improve their ability to operate well this summer.”

Airlines hope that limiting the number of flights will improve reliability and reduce delays. So far, it seems to be working. About one in every 70 U.S. flights have been canceled this year — half the rate of a year ago and lower than in 2019.

Limiting the number of flights also keeps prices above pre-pandemic levels.

A provider of travel data, Hopper, predicts that average domestic airfares will peak next month at $328 for a round-trip ticket, which is down from last summer’s record of $400 but 4% higher than in 2019.

There are some last-minute deals on domestic flights, Hopper found, but international fares are their highest in more than five years, with prices to Europe up 50% from a year ago.

The same thing is happening within Europe, as airlines hold the line on capacity at a time of strong travel demand.

“There is no expectation of seeing cheaper fares in Europe in the next seven or eight months,” says John Grant, an analyst for OAG, a U.K.-based travel-data provider.

For the travel industry, the big question is how long consumers can keep paying for airline tickets and accommodations while they try to deal with stubborn high inflation, news about layoffs and bank failures, and fear of a recession.

Industry executives say consumers are favoring the experience of travel over other types of spending, but some analysts see cracks in the strong demand for travel that began in early 2022.

Bank of America analysts say data from their credit and debit card customers showed a slowdown in spending in April, as card use fell below year-before levels for the first time since February 2021. They say spending on hotels, which rebounded relatively early from the pandemic, dipped this spring, while the late-recovering cruise industry is still steaming ahead — card spending on cruises rose 37% last month, although from very low levels a year ago.

“Travel remains a bright spot relative to other sectors, but we’re also seeing signs of moderation in the travel space,” said Anna Zhou, an economist for the bank.

PORTLAND, Maine (AP) — Recent shark bites in Florida and Hawaii and a suspected case in New Jersey have piqued interest in an age-old summer question for beachgoers — is it safe to go in the water?

Scientists and researchers who study sharks said the overwhelming answer to that question is yes, it is safe. Potentially dangerous interactions between humans and sharks are uncommon, and serious injuries and deaths from the bites are vanishingly rare, scientists said.

Nonetheless, the dramatic nature of shark bites and the stories of survivors, such as Hawaii surfer Mike Morita’s tale of fighting off a shark in April, capture the imagination. It’s a good idea to remember just how rare shark bites truly are, scientists said.

HOW OFTEN DO SHARK BITES OCCUR?

There have been typically around 70 to 80 unprovoked shark bites annually, worldwide, over the past decade. And not only are shark bites rare, they’ve been especially rare recently.

There were only 57 unprovoked bites last year, and five of those were fatal, according to University of Florida’s International Shark Attack File. There had been nine such deaths the previous year.

The shark attack file reported a year ago that one reason for the decline in bites might be be the global decline of shark populations.

It’s too early in the warm season to get an idea of how active this year will be for interactions between humans and sharks, said Greg Skomal, a shark expert with the Massachusetts Division of Marine Fisheries.

“If we get lots of bait fish and forage fish species close to shore, we have a super hot summer that draws people to beaches, more people in the water, then we can determine the risk,” Skomal said.

WHAT ARE THE MOST PRONE AREAS FOR SHARK ENCOUNTERS?

The United States and Australia are typically the sites of the most reported shark bites. Florida had more bites than anywhere else on Earth last year with 16 unprovoked bites, two of which resulted in amputations, the shark attack file said.

This month, two Florida fishermen were bitten by sharks in separate incidents less than 36 hours apart.

The rate of shark bites has stayed steady in recent years, but it might feel like a more common occurrence because of the prevalence of smartphones, said Nick Whitney, a senior scientist at the New England Aquarium in Boston. Recently developed smartphone apps allow users to report shark sightings in real time.

WHAT KIND OF SHARKS ARE CAUSE FOR CONCERN?

White sharks, bull sharks and tiger sharks are the sharks most cited by the International Shark Attack File for unprovoked bites. Those species are large sharks that also cause the most fatalities.

However, it’s worth bearing in mind that many interactions with sharks are with smaller species that are unlikely to cause serious injuries, said James Sulikowski, director of the Coastal Oregon Marine Experiment Station at Oregon State University. Those species might bite a human, realize we are not their preferred prey and move on, he said.

IS IT SAFE TO SWIM?

Yes. You’re at exponentially greater risk of getting hurt in a car accident on the way to the beach than you are to get seriously injured by a shark bite.

Millions of people flock to the beach in the summer as the weather heats up, and that raises the possibility of interacting with a shark. But by taking simple precautions, such as not carrying shiny objects into the water and not swimming at dawn and dusk, beachgoers can reduce any chance of a dangerous encounter with a shark, Sulikowski said.

“We are intruders in their environment. What we can do is be logical and safe about that and avoid areas where sharks are going to be feeding,” Sulikowski said. “When an interaction occurs, it’s mistaken identity — we are in an area where a shark is looking to eat.”
