This is good to bring on flights
This is good to bring on flights, for two uses: when the air is cold and dry, and you need to sleep, put it on and you will feel a lot more comfortable.  It keeps the air a bit warmer and moister, so you will stay healthy.  Also useful when someone nearby is coughing or sneezing a lot and you can't afford to get sick. It can also be handy for getting through extreme cold weather quickly -- easier to put on and take off than layers of scarves.
