I've looked at the baggage policies for carry-on bags, I've seen quite a range of shapes/sizes when I have flown, read stories that what gets on can depend on who's manning the check-in desk, seen opinions that so long as the LWH add up to less than 45" or so that it'll be fine, and also read a page that said even if the dimensions add up to the correct amount, that an odd bag (ex: 10x10x24) might not be acceptable.
Would you mind measuring your latest bag, giving its dimensions, and saying if it was acceptable or not?
This is all based on you only taking a carry-on (absolutely no checked; please forgive me if you see no need in avoiding checking bags) and meet the airline's weight limit(s).
Thank you in advance for your insight and examples of successful/acceptable sizes.
