Any statistics majors out there? How accurate is a poll of 9300 passengers, out of the tens of millions that flew during that time period. Delta carried 45 million pax during those months; other major airlines carried similar amounts. Nothing against JetBlue, but they're not a very big airline. How many of those passengers polled are even in a market served by JB? If the poll is skewed more towards one geographical area, the data becomes worthless.
Stories like this are good for filling a 20 second spot on CNN, but have no practical value.
