We were debating as to take an airplane or helicopter tour. We had some one person in our group who was 83 so we opted for the Air Ventures based on other positive reviews that it wouldn't be as bumpy as a helicopter. I would recommend Air Ventures. The plane was not too small, the pilot very knowledgeable of the entire island and each person has a window seat. If you are taking pictures, some seats in the plane are near the strut...which will end up in your pictures. My inlaws were seated on the left and back a row and their pictures were fine. There was some bumpyness but very, very minor. If you get car sick easily you may want to take some dramomine
