A white barf bag strategically placed in the seat pocket in front of you is a kind reminder that you are not the only person in this world suffering from motion sickness. While being in good company may help you feel better, there are some effective strategies to make the best out of your flight. Knowledge is ultimately power, and by knowing which are the best seats to help you feel a bit better, you may have some advantage over other motion sick passengers sitting in other seats.
First of all, let's point out the seats to avoid as much as you can. If you are prone to get motion sick, you want to steer away from the rear seats near the tail. The reason for this is that this area tends to be much more bumpier than other areas in the plane. It is not unheard of passengers in the front rows dealing with slight bumps, whereas those in the rear where subject to a roller coaster ride.
Simply, think of how it feels like when you are riding a bus and are sitting in the very rear while riding over a road full of potholes. Very likely, you will be bouncing around helplessly asking yourself why you ever ended up sitting there in the first place. The rear seats of a plane may look nice because they are likely to be less crowded and you may be able to reserve yourself a whole row of seats, but it may be noisy and particularly bumpy which is why those fond of turbulence like to hop on these seats in the first place.
