You might also have been on a plane that left the first airport with enough fuel +10 mins of flying time. The airlines are trying to cut out all excess weight and that includes "excess" fuel. How many times have airplanes been stacked up in the landing pattern for an hour or two or three? The lack of fuel means that they no longer have a choice about waiting for a storm to clear before landing. Now they will have to land regardless of onground weather conditions.

Some of the airline pilots are raising holy hell. There was a news blurb about it on the late night radio news that I listen to while standing my Bridge Watch.

I think I'll stick to my plan to minimize commercial flying.
