Airlines will be subjected to millions of dollars in fines after multiple flights were stuck on a tarmac for hours at John F. Kennedy International Airport this month. But none of the money will go toward compensating passengers who had to wait.

The fines are a result of the tarmac delay rule, which took effect in 2010 and penalizes airlines by imposing major fines if passengers are waiting on a tarmac for several hours at U.S. airports. It was designed to reduce long tarmac delays. Now, there are calls for the fines to compensate passengers, rather than go solely toward the U.S. government.
