This is a very long and difficult flight. By now for several years I swear to myself: "Never again. Why should I inflict this hardship on myself? Break the flight" And again and again I'm entrapped into picking up the fastest way from start to end. It is always tiring. Sometimes it is more than that, it is hurting and disappointing. This last flight was very disappointing. We purchased economy tickets but added 200 dollars per seat to get economy plus seats with more legroom. We do not need this legroom for our legs. We need it so that the guy behind us won't complain that they do not have enough room unless they touch our backseat. So what should I do if behind me part of the time is sitting a hyperactive boy who cannot stop knocking the screen on my backseat while playing games and when he is changing seats with his daddy the latter opens his tray and gets his 2 years old daughter to sit on the tray. When she moves, not only my backseat but rather my entire seat shakes. How many times can you request others to be considerate? This was a night flight but I could not sleep even for a moment. By the way, the boy and his daddy slept very well when they were not sitting behind me. What could the airline do in such cases? I do not know. What I do know is that it does not help me if the food and entertainments are good or if the staff is cordial and considerate. The ground staff was very helpful but after two hours into the flight, I already have forgotten that.
