A few months ago, the nice multi blue-hued blankets that United had to help you keep warm during flights started getting swapped for a dark blue thin guaze like material "blankets." I use quotes, since the new "blankets" didn't actually provide any warmth. On my flights the other day, I noticed that the flimsy blankets had been replaced. These new "blankets" can be best be described as being dark blue table cloths. So while not see-through like the last iteration, they still don't really provide the one thing a blanket is supposed to do: keep you warm. Even though planes tend to get chilly at cruising altitude no matter what time of year is, hopefully we'll get real blankets back in time for the Northern Hemisphere cold season.
