Q. I am a frequent traveler and make trans-Pacific trips 5 to 6 times a year. I find that I am consistently extremely cold during flights to the point that multiple layers of clothing, socks and a scarf don't cut it. The complimentary coach blanket doesn't do much either. Is there a reason that the temperature is so low during these flights? Can temperature be adjusted or are there temperature standards that airlines must follow? A. According to Corey Caldwell, spokesperson for the Association of Flight Attendants, temperatures can be adjusted on airplanes, but "there are no FAA regulations requiring specific ranges of high or low onboard temperatures." In fact, she adds, it's not always cold on aircraft. Flight attendants and passengers from all over the country, but especially the South, report that there are often high temperatures and humidity levels on the ground — and even in flight — during summer months. Passengers near doors and windows may feel more chilled during a flight, so opt for an aisle seat when you can. And always tell your flight attendant of your discomfort. He or she may encourage the pilot to turn up the heat.
