I am planning on going to Tokyo from USA via United Airlines for the first time. My carry-on bags and checked baggage are within the size limits, however, I have a problem with the personal item size limit of 9 inches x 10 inches x 17 inches. It is very small to fit my laptop back pack (16 inches), and I already have Targus Drifter II Backpack for 16-Inch Laptop that size 13.8 x 9.1 x 17.7 inches.
At a result, I have to buy the new laptop bag? (But I can't find it) Or will I have to pay this fee when I board?
