DALLAS (AP) — People began loading up their cars and jumping on planes across the U.S. on Thursday as the long Memorial Day weekend kicked off. Even as politics and the nation’s aging air traffic infrastructure rattle the U.S. travel industry, Americans were expected to get away in record numbers.

AAA expects 45.1 million people to travel for the long weekend, and Florida is a top destination for out-of-staters. Officials said the roads will be busy.

Despite some economic uncertainty, a record number of Americans are expected to hit the roads this Memorial Day Weekend, the traditional kick-off to the summer travel season.
