Kicking off 2022, CNBC’s Meg Tirrell discusses the latest surge in Covid-19 cases, up more than 200% in the last two weeks. 2021’s issues at the airport continue in 2022, as well: over 13,000 flights were canceled in the U.S. between Christmas Eve and New Year’s Day. CNBC’s Phil LeBeau reports on the latest wave of flight cancellations and says airlines have blamed the disruptions on a combination of bad weather and omicron infections that sidelined staff. While a problem for air travel, Covid-19 seems to be less of an issue for the fitness industry; CNBC’s Diana Olick reports on investor confidence in gyms, and Planet Fitness CEO lays out his own bullish perspective for the new year. Plus, Tesla’s had a big year. The electric vehicle maker beat fourth-quarter and full-year delivery expectations, and the stock is rising to match the success. Walter Isaacson, history professor at Tulane University, advisory partner at Perella Weinberg Partners, and the author tasked with writing Elon Musk’s biography, discusses the Tesla CEO and what we can expect from him--and his projects--in 2022.
