Re: "Flier Frostbite" [On the Spot, Aug. 31]: I work as in-flight purser from LAX to Frankfurt, Germany, and I consistently monitor the cabin temperature.
I try to keep it at 74 degrees in all cabins, but the readout on the gauge is not always accurate.
If I notice passengers huddled under blankets or wearing their coats, I know it is not 74 so I crank up the thermostat to, say, 78 to ensure it gets to 74.
My advice to passengers: By all means, let the flight attendants know. If they are rushing about, they might not notice the cold.
