McD and MsSmileee hit the nail on the head! Here's a suggestion, if you are flying at altitude at night, suggest you bring a jacket if the heater in the aircraft is U/S...can get rather cold, (beyond the point of keeping you awake!) Last time I was in up in the Pan Handle in early Dec, temp in celsius was single figures in the morning.
Enjoy it, I know I certainly did.
