I was on an evening United flight earlier this week and decided to change into nike basketball shorts, and a white tshirt. The first class flight attendant smiled at me and I clearly watched his eyes scan me from head to toe. I sat in the last row, isle seat in 1st class. He was very very friendly and would kneel down when asking me what I wanted to drink, and took his time explaining the menu. I was definitely showing VPL and whenever he would come over, kneel down to chat with me, I would get a semi. Later during the flight, he came over to chat with me for about 10 minutes. Most of the other passengers were asleep and the lights were off. I had the reading light on in the seat next to me to provide enough light to read without it being too bright so he had a clear view of what was now a raging hardon in my shorts. He would keep looking at it but never made a move to touch me. It was the hottest situation.
