N239JB. That's the tail number of the jetBlue plane Sarah Palin used during the campaign.
Hmmmmmm. I wonder if jetBlue would mention it to their customers before leaving the gate? If Obama had leased a jetBlue plane, you can bet jetBlue would not only tell everyone on the plane, but charge a premium for the seat he used while flying.
But hey, jetBlue is based out of New York, where Palin is not well-liked.
