I no longer fly on airlines anywhere.
The reason for this is because I can not kneel the heating plus A/C nor the air quality on planes these days.
It seems they have all got entirely cheap with the money they invest to supply the passengers indoor comfort. The air quality is consistently bad plus makes me choke or sneeze our face off, or the heating plus A/C is so weak that you are either frosty or guess prefer 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 our car which has a wonderful central heating plus A/C plan plus it can handle long road trips, or, I will take a train plus get a sleeper car. The heating plus A/C on trains I have observed are not great, but they are reasonable. 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 entirely expensive compared to flying anywhere plus also it can take you a month 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 plus take a long time to get anywhere in wonderful indoor comfort than have to deal with indoor discomfort for a whole day non stop on a plane with bad heating plus A/C!
