How strict is United Airlines First class with carry-on luggage size?
I have a laptop bag which I measured using tape and it fits within dimensions they mentioned in their website for carry-on item. I am still worried since I am not exactly sure how will they make sure carry-on luggage is of the desired size?
I don't want to convert it into check-in luggage because besides laptop it contains important items like my passport. Can I use carry a folder as my personal item in the worst case scenario?
