True, but it is from June 2017, hence why I said "recent". This thread by the way was started in early June 2017.
Another link is at https://travel-made-simple.com/carry-on-size-chart/
. Scroll down for the size/weight chart which is a bit more useful in that conversions from "English" to metric units are accommodated and if you click on the airline you will immediately get the most correct airline specific information.
I'm not quite sure of the point you are making. The links you cite are certainly useful, though June is several months ago.
The point I'm trying to make is that we have an actual user experience that is more recent. Some airlines enforce their rules more than others. For example, United Airlines has dimensions listed for carry-on, but in practice, it seems that "if it fits, it ships" to steal a phrase from the US Postal service. I've been flying UAL a lot this year, and I'm amazed at what some people consider "carry-on". On Lufthansa, it seemed that a back pack, even if larger than the permitted sizes, can go on carry-on, 2 years ago- I don't know if they became more strict now. While I don't recommend taking large items (there is limited space and it is impolite to others that do follow the rules), it is nice to know which airlines are strict and who allows a bit of flexibility as long as one isn't a total fool about it.
