I bought two of these in a rush as we needed them for a family trip, and this model was in stock vs. the spinner. While I wish the 4-wheel 21-inch model would have been available in time (that one is listed as: Case Dimensions: 21 inches x 14 inches x 9 inches; Overall Dim: 23 inches x 14.5 inches x 9 inches; Weight: 5.4 lbs, Vol: 46 liter) , this 20-inch model actually is closer to the Ryanair specs as of August 2022.(TravelPro does offer an "international" 19-inch spinner model on its own site, but that one has slightly less capacity at 39L and was not in stock within my timeframe. Specs: Overall Dimensions: H: 21.75 in. W: 15.75 in. D: 7.75 in. Case Dim: H: 19 in. W: 15 in. D: 7.75 in. Weight: 5.3 lbs. Vol: 39 L)I'm happy to report that this 20-inch two-wheel style met Ryanair's specifications with nary a second glance. Ironically I was forced to check it on a Delta/KLM codeshare, because the flight was very full. The Azure Blue looked pretty much good as new when it showed up on the carousel, despite being checked onto two connecting flights. Post-trip pic attached - any color variation in the full-length pic is due to shadows, not dirt. Azure Blue is actually a nice warm blue, first pic is just a little overexposed due to afternoon sun. See second photo for color comparison.(Actually the bag looked better than my also brand-new hardshell American Tourister (ABS) spinner which was checked on the same flights and emerged with several long scuffs. But they both did the job which was to protect my belongings and remain intact.)I appreciate that this TravelPro has some higher-end features: all the zippers, even the ones on the interior mesh divider, are two-way (i.e. not just a single one-way zipper); the telescoping handle has two height adjustments; the wheels run smoothly and in fact track so well that you can push the bag down an aisle instead of pulling it, allowing for more maneuverability; the grab handle on the bottom makes it easier to move when loading into an overhead compartment; it's stable and not tippy even when fully loaded and with extra bags resting on top. It does not have locking zippers though you can use a small padlock to secure the zips. My one caveat is that I wish the side grab handle was oriented vertically or diagonally when the bag is standing upright, instead of horizontally. That would make it easier to grab when it is lying on its side (e.g. on a carousel) or to carry when walking in close quarters, as if it were a briefcase.Last thing that I really like about this bag is that it is quite light (5.4 lbs, vs. other similar models from diff brands which can clock in at up to 8.2 lbs), which makes it far easier for me to hoist it over my head. I am >5 feet tall so when I put it into an overhead bin I need to stand on the seat or lift it in a full overhead press, so every ounce saved matters to me. Plus of course the lighter the bag, the more capacity I have for my belongings.Quite happy with this purchase!
