So, unless very close to departure dates, I would not go out of my way to book a flight currently scheduled on 77W for any JFK or DFW route.
Since LAX-LHR has only one flight, I would feel more confident that once 77W starts servicing this route aircraft changes will be very unlikely.
Having said that, personally, I put a lot of value on my time in the ground and on my precious personal/vacation days. So I would not waste more than 8 hours just to try the 77W.
I don't agree. Unless there have been actual cases of the 77W swapped for a 772, there's no reason to believe AA will do so arbitrarily, out of the schedule. Maintenance issues can of course happen, but AA at LAX has quite a few 772s as well (to Asia and to MIA).
Though I will agree that it's not worth the time wasted just to fly the 77W.
