(AP) – The Memorial Day holiday weekend has produced the two busiest days for U.S. air travel since early March 2020. The U.S. Transportation Security Administration says about 1.96 million people passed through U.S. airport security checkpoints on Friday, and 1.90 million did so on Monday. Tuesday was also expected to be busy, as travelers returned home after the Memorial Day weekend. Analysts expect travel to continue rising slowly now that many Americans are vaccinated against COVID-19 and airlines are adding more flights. Last month, the number of people screened at U.S. airports was down one-third from May 2019. (Photo: CNN)
