As a kid, we never flew first - except to Hawaii on United. We'd head over with my aunt's family and between both families we'd take up a big chunk of first. I believe my mother and aunt did it because of the mai tai's :-), but I can't report on those because I was too young...
However, someone in the family always won the "guess when we'll be halfway there" contest - which made us kids really excited even though the prize was bad champagne (which the adults had to then lug to the hotel)
Funny thing - we mostly flew American or other carriers - but to Hawaii...it HAD to be United...
