Now rolling out with no word here from UA Insider is UA's new enforcement of carry-on size limits. I've read that they are showing up at DEN, LAX and CLE. Not sure about other locations. Sounds like they are giving the GAs the power to make you pay to check anything that doesn't fit into the sizers, even though they are known to fit just fine in the overheads. Is Smisek trying to run off ALL of UAs customers and start over from scratch? Mine aren't technically legal, but my hanging bag fits perfectly into anything from an E190 up. My laptop case gives me trouble in F/J, but that's just because of the electronic junk stuffed under the awkward seat braces. It fits fine in E, even on RJs. Does UA management really lack the ability to see the steam coming out of our ears already? I think I may just quit flying.
