This is a tricky one. I think a few v-flyers have mentioned this before, when the news of the route changes were first announced. I have flown this route a couple of times so far, and the load has varied from half full to overbooked. The prices on this route is pretty competitive, too.
Part of me thinks that this route has survived the last round of changes due to the slots at LHR. With the late departure, I don't think they would be any good for TATL flight.
I do hope that it survives long-term, as I use it for fairly regular work trips, but I am not going to hold my breath.
