BTW, quick side note on that 8:21 pm EWR-DTW departure - I have yet to see it operate on time anytime I've been at EWR. As it is, all three NYC airports are delay-prone, and being that late in the day on a short hop route yields a high probability for an ATC headache. If you're just going to DTW, it's not a big deal, but a watchout if it's a flight you're going to be connecting from in DTW.
