You're right, I think it's D. I've been looking at the class availability tool and there are a couple of options on the day to Newark (which I never mind arriving at) or early to JFK that have availability in D class so I'll book those. Nearer the time you never know there may be a shortage of high-rolling execs that day and I get confirmed on a reasonably-timed flight at my cheap business fare. $2300 is a good fare, mine are usually $3300-3500 for New York return I think.
