What's making airline passengers act out on planes? Travelers are stressed out and feeling 'entitled,' experts say.

• The stress of air travel may have something to do with unruly passengers in the skies. 
• "Increased stress pretty much always results in a shorter fuse," an aviation expert said. 
• This year, the FAA recorded more than 1,900 "unruly passenger" reports, well above pre-pandemic levels. 

It seems like every week there's a new story of chaotic and unruly behavior by plane passengers making headlines or going viral on social media.
