Airfares are almost certain go up this summer. Troubles with the Boeing 737 Max are part of the reason.The grounding of the Boeing 737 Max jet took 371 planes out of service worldwide for an indefinite period of time. Boeing also halted deliveries of new jets that could have been in service by the time the peak summer season arrived. Discount European carrier Ryanair had been awaiting its first 737 Max when deliveries were halted.Among 737 Max's largest customers are discount airlines, like Southwest in the United States and Norwegian Air in Europe. Those carriers put pressure on fares, forcing other airlines to offer more seats at lower prices to compete for leisure travelers. Fewer flights by discount carriers mean less competition for other carriers, and less incentive to offer lower-priced seats on their planes."I think it certainly has the ability to pressure fares higher as we get into the busy summer months," said Helane Becker, airline analyst for Cowen.Uncertainty over when the Boeing 737 Max will be back in service has led airlines to cancel hundreds of flights a day all the way into August. Southwest canceled flights through August late last week, and American Airlines, the world's largest carrier, did the same on Sunday. United Airlines, the third US airline with a version of the 737 Max in its fleet, has canceled flights through early July.United on Tuesday trimmed its estimate for how much its capacity will grow this year. It expects to grow by up to 5% growth, down from its earlier forecast of 6%. It also said it expects sales from passenger fares to be up 2.5% in the April through June period.Summer is the peak travel season for airlines. They put as many planes in service as they can, which means fewer extra planes will be available to fill in for the missing 737 Max jets."All the airlines have some extra planes at any period of time. But in the summer the system is strained more tightly," said Philip Baggaley, the lead credit analyst for transportation companies for Standard & Poor's.The 737 Max problems aren't the only reason fares will be higher this summer. A strong US economy, with near record low unemployment has increased demand for travel. And higher jet fuel prices limit routes that airlines are willing to fly. "It's tough to disentangle the impact of the 737 Max from the other factors," said Baggaley.When jet fuel is lower, airlines will add flights on routes where they might not otherwise be profitable, which adds to passenger choices and can push down fares. The opposite happens when fuel prices are higher. Fuel prices are about 20% above where they were a year ago, and prices are expected to climb higher in the next three months.Europe doesn't have as strong an economy as the United States, but a number of budget airlines have gone out of business in the last six months, including Wow Air, Primera Air and FlyBMI. That means less fare competition, allowing fares at other carriers to rise.All of Boeing's Max planes were grounded worldwide last month after a 737 Max jet flown by Ethiopian Airlines pilots crashed in that country, killing everyone aboard. It was the second fatal crash involving a Max in recent months. A Lion Air flight crashed in October.Investigators believe the crashes are tied to an automatic safety feature of the new jet that forced its nose down.It's unclear when Boeing will get approval for a 3449

A wildfire is burning out of control north of Los Angeles, forcing thousands of residents to evacuate their homes, fire officials said.The Tick fire near Santa Clarita broke out Thursday and in just a few hours has burned about 3,950 acres, the Los Angeles County Fire Department said. It was 5% contained by late Thursday.The wind-driven blaze had only scorched a couple hundred acres when it quickly exploded to more than 3,000 acres and destroyed several structures, the fire department said.The cause was unknown.The Agua Dulce area, where the Tick Fire is burning, was part of the ongoing intentional power outages, said Lois Bruce, a spokesperson with Southern California Edison.The area was de-energized at about 8:50 am (local time) and blaze started at approximately 1:45pm, Bruce said.Wind speeds in the area are sustained at about 15 mph, with gusts of roughly 30 mph, the National Weather Service said.Mandatory evacuations were ordered for homes in the northern area of Los Angeles County and several shelters were opened.An animal protection nonprofit was scrambling to evacuate animals from their farm in Santa Clarita as a large plume of dark smoke was spotted near the property."Please support our efforts to activate our emergency plan! We can use all the help possible" the Gentle Barn wrote on Instagram.The group later wrote they were able to transfer all animals out of the barn after they were ordered to evacuate.Firefighters across California are battling several wildfires.In Northern California, 1535

A woman who gave birth alone in her jail cell in Denver is suing the city after jail deputies and nurses allegedly ignored her pleas for help during about five hours of labor.Silent surveillance video released by her lawyer shows Diana Sanchez eventually lying down on a narrow bed, crying out in pain, before she pulls off her pants and deliveries a baby boy in July 2018.The federal lawsuit filed Wednesday says a van was requested to take Sanchez to the hospital. But jail workers knew the ride likely wouldn't be available for hours until after the morning booking process was finished.The Denver County Sheriff's Department said Thursday that it has since changed its policy to ensure that pregnant inmates who are in any stage of labor are immediately taken to the hospital. The agency declined to comment on the lawsuit. 839

Across the country, more states are legalizing marijuana.Now, more people are opening up about getting high and getting behind the wheel.“I feel more focused than when I’m sober,” Caleb Occelin said of driving while under the influence of marijuana. “It eases my mind. It makes me focus on everything.”Others, however, say they know better than to mix cars and cannabis. “Do not smoke weed and drive,” said marijuana smoker Sam Lee. “We all know we can barely think straight instead of drive.”Now, a team of medical professionals is studying the dangers of smoking and driving.“There’s been increasing concern about the potential of public health impacts of people using cannabis while they drive or shortly after,” said Dr. Michael Kosnett of the University of Colorado Denver.Kosnett is teaming up with Rocky Mountain Poison and Drug Safety on a study about the effects of cannabis while operating a motor vehicle.This study tests three focus groups: daily smokers, occasional smokers and non-smokers as they go through tests measuring reaction times, hand-eye coordination and short-term memory.More than a year into the study, the team has hit an unexpected road block: they can’t seem to find occasional smokers.“As for people who just used it occasionally, like on a weekly basis, that was probably less than one-fourth of the people,” Kosnett said.This study is still in process. Kosnett has not yet released the findings.Denver Police Sgt. Alan Ma, however, doesn’t need to know the results. He says he knows from working his nightly beat that driving high is dangerous.“Their perception and reaction times are delayed,” Ma said about people who drive while high on marijuana. The Denver Police Department wrote 63 citations in both 2016 and 2017 for marijuana-related DUIs. 1794

A transformer explosion at a power plant in Queens temporarily lit up the New York City skyline in a brilliant blue Thursday night.But despite the eerily glowing color, an alien invasion it was not.Instead, the light came as part of a brief electrical fire after a "couple of transformers tripped offline" at the intersection of 20th Avenue and 32nd Street in Astoria, Con Edison spokesman Bob McGee told CNN.The issue caused a transmission dip in the area, and Con Edison crews responded with the Fire Department of New York, Con Edison said.The incident is under control and no injuries have been reported, the FDNY said. The explosion was determined to be a non-suspicious equipment malfunction, according to a tweet from the NYPD 114th Precinct.There are no significant reported power outages anymore, New York Gov. Andrew Cuomo said."No injuries, no fire, no evidence of extraterrestrial activity," the 920
