I don't know. Best downgrade ever for me was on Delta, LAX to ATL. Nice FC seat, get on plane, get called to the jet bridge by the CSA, "I'm sorry Mr. Miles, but the person in your seat actually did check in. We'll have to put you in Y."

Yes, but this was like the first month of BYOB, it's 1730, I'm hungry and I tell the agent I don't have any cash to buy food.

"We'll get you the FC meal," he says.

So I end up in the first row in Y with a boatload of leg room, and yes, they did give me the FC meal, which was really, really good.

Oh, and a fistful of drink chits, which I handed out to my seat mates, big spender that I am.

[So why was I flying Delta? VERY last minute business trip, came up late in the day, needed to be in ATL early next morning and this was the only way that made any sense at all.]
