The last time I flew 1st Class transpacific I had a male flight attendant lead with several mature females. The iconic stewardesses of the 60s are long gone.
However, I find the Asian Airlines (Cathay Pacific, Japan, etc) to have very sexy attendants. Plus they are very helpful.
I had to run to make an AA flight to Tokyo and was the last passenger to board, had the last Business Class seat next to the kitchen. Needed something to drink (juice, water, beer) from the run, had to wait over 30 min to be served.
