OK, this is not my opener but last time I was in an airport I had this epiphany:
The Cologne Opener is GREAT for airports! I usually don't use other people openers and I think this one is lame for a club or bar, but it makes PERFECT sense for an airport where so many people are buying colognes. Just show up 3 hours before your flight and open 30 sets with it
then transition to: "So.... where are you flying today..." "oh really..." bla bla bla.
