The TSA said that 1,369,180 people passed through security checkpoints on Saturday, a day after flying passengers set a new pandemic record by passing through TSA security with 1,468,516 people. For health professionals, this is a concerning sign: Despite the fact that millions of Americans have been vaccinated, the US Centers for Disease Control and Prevention nevertheless advises against traveling. It has so far declined to publish fresh travel advice for vaccinated Americans, citing concerns raised by travel-related spikes in the United States during recent holiday seasons. “We’ve seen surges after people start traveling, we’ve seen it after July 4, we’ve seen it after Labor Day, we’ve seen it after the Christmas holidays,” CDC Director Dr. Rochelle Walensky said last week during a Covid-19 briefing in response to a question from CNN’s Kaitlan Collins.

However, investors are becoming more upbeat: Southwest (LUV), Alaska Air (ALK), JetBlue (JBLU), and Hawaiian Airlines (HA) all have stock prices that are higher than pre-pandemic levels, while American (AAL), Delta (DAL), and Spirit (SAVE) are close to that level. Only United (UAL) stock is much lower than it was in late January 2020. This story was co-written by Chris Isidore, Pete Muntean, and Gregory Wallace of CNN. Continue reading
