 Airlines are bracing for the busy July 4th holiday travel crush. The TSA's six busiest days on record have all come since late May. For Deanna Gabriel-Varique at Denver International Airport, it was so far so good. It's been super easy. Like, no hiccups, no trouble. There's no lines at security. I got right in, checked my bag. Super smooth. Speaking to KMGH, TSA expects to screen more than 32 million people through July 8th, up more than 5% from last year.
