Standiford Field
 

So I'm heading straight from this year's Derby to Mexico. Don't ask why, long story. I figure I'd just check out flights from Louisville, but wouldn't you know it, it's like 10 times cheaper to fly out of Lexington than Louisville. Why the heck would that be?

I think the planes out of Louisville have to burn more fuel to get off the ground, what with the mane on the back of the plane and the huge flowing tail hanging from the rear. These things create drag. You might also want to notice how the pilot is dressed. Drag might cost extra.
I could be incorrect, but I don't think fermenting the oats to supply a biofuel will work. Jet farts...and all that.
If the plane sounds like a "gallop" going down the strip, you might want to jump off before it hits the end of the runway, or the quarter pole.
Happy landings!
