It is funny.
I noticed them about a week ago on a UAX flight. I was going to snap a picture and post about it, but something must have distracted me as I forgot all about it.
It is actually a bit understated, in a good way. Just the United logo without any marketing drivel.
I hated the old napkins and turned them over to be just plain white. In fact, on one flight I had a little game going with my FA on a TPAC flight. She would always turn them back over whenever she served a drink.
