I have never had trouble carrying on the 27in Purdy Neat bag however, I am always in uniform, I think that makes a huge difference.
The matching tote bags can be found on the website.
I am on my second Purdy Neat(1st 23in), these things last for years. The competition((if you can call it that(flt attendant bag)), you'll lucky to get a year out of it before it starts to fall apart. I speak from experience I tried it in between my Purdy Neats.
