With the recent wave of moves with carry-on bag sizes, I've thought "why not just buy stock in Tumi and go out and bag some new bags?" My bonus check coming in a few weeks anyway, and the new bags look nice. BUT, I want to find something that is compliant on all airlines now. Has anyone seen a comparison chart for major *A and OW carriers? I fly Swiss a lot, and they can be bag haters, but hey... They serve good chocolate in business. But I also fly OW (air berlin and BA) quite a bit. It's just a crap shoot sometimes depending on airport and airline. Would love to find the larget compliant bag I can buy since traveling for 2 weeks on end, flying nearly every day, really would suck if I had to start checking bags.
