There are two types of trollies, ones that are more vertical and ones that are more horizontal:
I would like to know if in practice does it matter if a cabin trolley has it's wheels on the short or long site (of course assuming both have the same volume)? Is one geometry better than the other?
I could imagine that the horizontal one has a longer handle and the handle might be divided into more segments to fold it up. I could image this makes it more likely to break? Is this true?
Observing other passengers, it seems that the second type seems the high version seems to be more frequent and if the wide version occurs the owner seems to be male. I wonder if there are reasons for this.
