If your personal is too big and large it will be considered a carry-on.

Make sure the personal item is small and it can be placed easily under the seat in the airplane.

Keep in mind that if you are traveling with a carry-on and a personal item, especially if your personal item is a duffle bag or a small backpack, you are going to attract the attention of the airline staff at the airport.

And in busy flights where the space in the overhead bin is cramped you may be required to check in your carry on bag.

If you are traveling with two items but want to maximize your luggage, by packing one carry-on and a larger duffel bag you might be asked to gate check one or both of your bags.
