Flying on an airplane can be fun. Flying on first class is desired by many. If my family and I ever decided to fly across the country, we would definitely choose first class (if having the resource). One thing I know for sure is that we would never fly on different planes.
Prices change every now and then. You never know when there will be an incredible discount, (as it happened to us a few years ago). I guess I can say that throughout time as technology advances, flying prices will go lower. We surely cannot erase the idea of flying cars replacing airplanes.
