I no longer fly on airlines anywhere.
The reason for this is because I can not stand the heating and air conditioning nor the air quality on planes these days.
It seems they have all got really cheap with the money they invest to give the passengers indoor comfort. The air quality is always bad and makes me choke or sneeze my face off, or the heating and air conditioning is so weak that you are either freezing or feel like you are in a small oven. I’m not having any of that anymore! It is so uncomfortable to me I simply can not deal with it any longer. When I travel I end up either taking road trips in my car which has a great central heating and air conditioning system plus it can handle long road trips, or, I will take a train and get a sleeper car. The heating and air conditioning on trains I have noticed are not great, but they are acceptable. Also the air quality is a lot better cause you have more space in a long distance train ride with sleeper cars in there. Sure it is very expensive compared to flying somewhere and also it can take you a week or more to get across the country on a train versus the 8 hours or less it would on a plane. But I would rather pay the high dollars and take a long time to get somewhere in decent indoor comfort than have to deal with indoor discomfort for a whole day non stop on a plane with bad heating and air conditioning!
