Last time I flew Delta they no longer had this bot, which made me sad. One of my favorite parts of flying was getting absolutely crushed into a tiny cube by the airplane seat's easy chess bot, and then again by the airplane seat itself when the person in front of me reclines their seat.

There's a bug in the Delta Air Lines chess program. After cxd6 en passant, the captured pawn isn't removed [0]. White's bishop is then able to check the black king through the pawn (the pawn that should have been removed) [1].

I wonder if they gave the chess bot X seconds of thinking time in an era when computers were slower?
The way you set difficulty for turn based game ai is that you limit how far ahead the algorithm searches. If you set the lookahead based on compute time your difficulties will be way out of line if someone upgrades the CPU.

In short: it plays far too well (~2500 ELO.) People think it originally played at a reasonable level and accidentally got more powerful as the seatback computers got more powerful; the same thing happened to the Mac chess app with the release of the M1.

Is this really true? I played a few games with it in August. It's not very good.
It's one of those old programs where 95% of the moves are pretty strong. But if you just do nothing and sit back it will occasionally make a random blunder and then you grind it out. I figured it's how they were able to weaken a chess engine back in the day; can't adjust the overall strength, so add random blunders.
I'm only about 2000 on lichess but I beat it pretty much every time, especially once I realized there is no reason to try anything sharp.
