This will be my first post to Sky Jinks Blog. I incourage readers to comment with their airline jokes and stories. This first story comes from the opening paragraph
of "Wheels Up."  

Delta was taxiing out for takeoff. United had just landed and was

on her way in. As they passed on the taxiway, Delta Captain McSwine

shot the United captain the bird and at the same time picked up the

phone and addressed the passengers. "Ladies and Gentlemen, off

to your left you will see the friendly skies of united." They all looked

in time to see the united airplane slowly taxi by while its captain, in

plain view, returned Captain McSwine's insult.
