This week, thousands of families in Minnesota will take to the skies and highways, thanks to the annual teachers' union conference.
Known as MEA weekend (short for Minnesota Educator Academy), the block of time away from work means many families with school-age children will flock to the Minneapolis-St. Paul International Airport for a fall vacation.
"MEA week is typically one of the busiest weeks of the year at the airport, with many families taking advantage of the kids' time off school to take one last vacation before the snow flies," Phil Burke, director of MSP Airport operations, said in a statement.
Security screenings are expected to surge due to increased passenger traffic, according to Lorie Dankers, spokeswoman for the Transportation Security Administration (TSA).
On an average day, the TSA screens about 34,000 passengers at MSP. The busiest day so far this year was March 10, with some 47,300 people screened.
On Wednesday and Thursday, the numbers are expected to increase to more than 43,000 travelers screened a day.
"The biggest push has been Tuesday afternoons and Wednesday," Dankers said. "However, with the change in school district calendars, this year we saw a surge on Thursday and Friday and again over the weekend. [It's] hard to differentiate among all the passengers, but we know that MEA is a big factor."
Some school districts have the entire week off, including Burnsville-Eagan-Savage. Minneapolis Public Schools and Anoka-Hennepin district schools have Wednesday through Friday off, while St. Paul and Osseo-Area schools have just Thursday and Friday off.
