If I don't expect the plane to be full, then it's rational to prefer (e.g.) a 50% chance of having all 3 seats, a 45% chance of aisle+middle, and a 5% chance of aisle+window with middle occupied (that's assuming 10% won't switch with window, which I think is a high estimate) over 100% aisle+middle, and 5% of that time the window remains empty.
