Departure was already delayed an hour and a half before we boarded, then it took an hour and twenty minutes to taxi to the runway at JFK. During the two hour flight to ORD they didn't turn the seatbelt sign off once, even though it was as smooth as silk the whole way. Do you think that people are just going to sit in their seats for three hours and wet their pants? Do you think that the cabin crews stop them from walking around? If you feel that you get no respect from the back, try giving to them once in awhile!
