While I do have sympathize with those stuck on that Jet Blue flight for 8 hours at JFK, I think passengers who whine about delays, when it comes to flying are not being realistic.
They obviously never heard of the saying, "it's better to be on the ground wishing you were up in the air, then being in the air wishing you were on the ground."
Should be a slogan in large bold letters on the back of every ticket sold. And in red neon lights on the the seat back in front of them.
