For anyone looking for a bargain carry-on right now, I ran across
this yesterday while looking for something to downsize our bags for a vacation that includes a few European regional flights. Bought two.
As I measure, it comes in right on 5 lbs, & 19" x 13" (maybe 13.5" to outside of wheel guards) x 7" (expandable another 2"), overall, including wheels...might could be squished in another 1/2" each dimension if you had to.
Obviously, it's not super heavy duty, but it appears sturdy for what it is, and has a surprising number of decent features: Formed metal interior frame about 1-1/2" wide that runs the center of the full perimeter and backs up the side & top handles. Interior curved sheet-plastic corner stiffeners & wire-frame edge supports. Two flat zippered exterior pockets & a larger one behind them on the interior (mostly for fairly thin things). Two snap-release buckle interior packing straps & a heavier exterior strap/buckle to secure another small bag to it. "Skateboard" wheels. Pull handle that extends up to 24", with several stops in-between.
Sorry, not trying to sell them, just wanted to provide details since websites are often short on in-depth details.
On sale at only $20 ($18 if you order online w/code
CUPID in the next couple of days), I considered it a deal if it only lasts thru the one trip, & it seems tough enough to make it longer if you're not too hard on it.
Hope this is useful to someone.
