If you buy yourself a ticket on Comair Flight 5283 you'd better bring a book.
Perhaps "War and Peace" or something just as long, because the plane from New York's Kennedy Airport to Reagan National in Washington has a tendency to be late.
In fact, figures from the Transportation Department show that during September, Comair 5283 was late 100-percent of the time.
On average, it was one-hour and 19-minutes late.
The scheduled flying time is only two minutes less than that.
Twenty-five of the nation's 50 most frequently delayed flights in September were on Comair to or from JFK.
Officials say chronic congestion in the New York skies is one factor.
So is the financial turmoil at Comair's parent, Delta.
