Thank you all so much for your replies.

Steve64, I agree with the other poster that the reason for your sore throat is likely the dry air. I bring a child-size (only size that meets tsa requirements) saline nasal spray onboard and that really helps. I read somewhere that using the air nozzles at full blast can actually help prevent catching covid or any other respiratory virus as it creates an “air barrier” in front of your face. Probably not worth your discomfort but it’s a thought. I’m sorry I don’t have a link for the article as I read it over a year ago.

Sluggoaafa, thank you very much for this insider info. That’s interesting re same settings yielding different results.

stant, I absolutely agree with your take on the gentleman’s situation. And 80 degrees Fahrenheit is absolutely too warm. Some people with asthma and other respiratory problems can start having difficulty breathing when it is that warm.

Cova, I also can sleep better in a cooler environment. Most people sleep better in a cool environment versus a warm one. Various studies bear this out.

Magnum9, I couldn’t agree more. I, too, appreciate the fact that most U.S. airlines have aircraft that allow individuals their own air nozzles to adjust as they please. I am much more comfortable on these flights. However, the problem was present on aircraft with individual nozzles. The air coming out was warm or lukewarm instead of cool or cold. It also seemed not to be coming out at full-blast.

VSLover, that sounds miserable. It was smart to begin traveling with a device to measure temperatures. And, of course, I agree with your summation that those of us who are hot can’t do anything about it versus others who skew cold.
