Hi everyone, I'm heading to Vegas next month, flying United out of Newark. I'm only packing in carry-ons, but I'm having trouble trying to maximize my space on a limited luggage budget. I tend to road trip to destinations, so I don't want to spend a ton of money on luggage at this time to use on rare occasion. My usual vacation bags are slightly off on dimensions, and of course I am less limited on bags when I travel by car. United's max sizes are: 22 x 14 x 9 for a carry on and 17 x 10 x 9 for a personal bag. To be noted, I have a 15.6" laptop that I hope to be able to fit as well (15" x 10" x 1" actual laptop dimensions). Does anyone have any suggestions for budget-friendly luggage in these sizes, preferably that will maximize my space without requiring me to check a bag? Internet searches are driving me insane, and I'm a little tired of searching around Amazon and reading mixed reviews and dimensions.
