More than 1.3 million people took to the nation’s airports over the weekend to head back home from Christmas and New Year vacations, the most travelers seen since the beginning of the COVID-19 pandemic.

Sunday’s traffic capped a 17-day holiday travel period where nearly 18 million people started travel at U.S. airports, according to figures from the Transportation Security Administration.

While those were big days for 2020, airports were welcoming more than twice as many passengers in 2019.

From the beginning of March through the end of December, passenger traffic at airports nationwide fell 72.3% and analysts are expecting airline losses to top $35 billion for 2020.
