Thanks for sharing this! It was thoughtful that someone included in the thread an extensive listing of bags found to be compliant and the date they were reported, but much of that info is almost ten years old now. And in that time the market for carryon bags has changed dramatically, with the increased popularity of spinners, so it's now difficult to find two wheel bags at all, let alone reasonably priced bags that comply with United's size requirements and are reasonably priced. If anyone knows of any (other than the Rick Steves' bag), please let me know!
