I have a rolling brief case that should fit under the seat, and it will. I will give some forwarning, however. One of the scarier incidents I have had involved a trip on which I took that rolling brief case. This particular flight was on ATA from Indianapolis to Orlando about 3 years ago. On this flight, my husband was separated from my then 5 yo son. We were in the last row of the plane, he was toward the front. We were hoping to swap seats with somebody in our row so my husband could sit with us, but, my row mates behavior disuaded me from doing so. There were several minor incidents involving these people. First of all, the people in the row in front of us were sitting in different seats than those to which they were assigned. This was so that their family would be seated together on the same side of the plane. The people who were originally assigned the seats arrived later, and insisted to the point of near-violence so that security was called and boarding was postponed that the people move and let them have their assigned seats. Now, mind you, these were identical seats in the same row directly across the aisle from each other. It would make no difference at all to me if I were on the left hand side of the plane or the right hand. But, apparently to these individuals, it was a life-threatening crisis. Then, when I had my brief case totally under the seat, apparently, the woman in the seat in front of me could feel it with her legs. This was the same woman who had moments before threatened another person with physical violence because she may have had to sit in 33A instead of 33F.
So, that rolling brief case was hefted into the overhead bin. I sure could have used hubby then. So, even if the dimensions indicate that a particular item will fit, an ultrasensitive row mate might make it necessary to put the piece into the overhead bin.
