I was on a flight from PHX-PHL a few months ago (I 8C, a couple 8A/B). The man had his hand up the woman's skirt. They reeked of alcohol. Comments through the flight included "I'm glad I called you and you could come on this trip; your airfare was cheap." During the trip, he wrote the woman a check and said, "thanks again." Not to mention the 5 Jim Beams and 4 Chardonnays the woman purchased. I just kept giving the FA looks as he served them repeatedly...
