Transcript for Carry-On Bag Offenders Called Out in New Hashtag
We're back with one man's campaign against the travelers who take advantage of the fellow flyers by taking up the carry-on space. He is taking to social media and says to post photos of the carry-on hogs, with carryonshame. Reporter: For any frequent flyer, the only thing you want to hear is we ran out of bin space. Look at all these pictures on Twitter because beware, this morning, there are eyes in the skies. We've all seen them. Or even been them. Those megastuffed, oversized carry-on offenders. "Saturday night live" even spoofed them. It will fit. Oh, it will fit. Reporter: But this morning, watch out. Your carry-on offense might be called out, with the hash tag that's going viral, #carryonshame. We're not just looking at the people who are bringing too much stuff onboard. We're looking at the airline that is not enforcing the rules that they already have. Reporter: San Francisco chronicle travel editor, spud Hilton, is leading this new campaign, with his blog, "Bad latitude." We all get a little self-on Sa absorbed.

First, check your airline's carry-on dimensions and restrictions. Wear your heaviest clothing on the plane. And back clothes in plastic bags, squeezing the air out before sealing can save you inches. If you have to take some shoes with you, take your socks and put them inside. You're using it as a compartment. And you're not wasting any space at all. They need to take less stuff. Or they need to just lump it and pay the checked bag fee. Reporter: That fee. And just to be clear, we're not urging you to shame your fellow travelers. But go ahead and tell us right now on Twitter, all of your carry-on packing tips right now. At "Gma," and use #socialsquare. I might encourage them to do it. Thanks, guys. And coming up, we're going to take a close look at the
