(I already posted about this today but when I edited the topic title, my post got deleted. So I'll post my question again, in much shorter form)
I'll be flying between Italy, Germany, Greece, and Malta in a couple months (via Lufthansa, Aegean, and Malta Air) and am considering getting carry-on luggage so that I don't have to deal with wait for baggage claims.
I've been looking at TravelPro Maxlite 5 Spinner cases and see a couple sizes: "21-Inch" (which is really 23 x 14.5 x 9 inches) and "20-Inch" (which is really 22 x 14 x 9 inches). The first one has a volume of 46L and the second one is 38L.
For flying in Europe in 2026, are these equally likely (or unlikely) to be accepted as carry-ons? Or is the 20-Inch model signficantly more likely to be accepted?
And are there alternative designs with good volume but different wheels or handles which add fewer extra inches?
What would you buy if you wanted to avoid having to check your bag?
Thanks!
