To give you some more info:
I had experiences with pheros on the plane, both good and bad. Good was when I had this really beautiful and smart blonde girl who struck a conversation with me. I gotta say, I looked really ugly that day according to my standards, but residual Ammo from the previous day was more than enough to get some results. There were definite IOIs. Honestly wished the flight to be longer.
The bad: some guy who drank beer and coffee and trying to grab your attention. I was wearing P74 and IS that day. You better hope your plane lands fast!
