About to book a flight to EZE for next August in J. According to aa.com, as of now, the 2 MIA flights and the DFW one are planned to be on old config 3-class 777s whereas the JFK one is on a 2-class 772.

This would give the edge to the JFK flight. My thinking, though, is that, 10 months in advance, it is well-nigh impossible to second-guess which equipment will be flown on any of the three routes so that I might as well ignore this and just go for the schedule which works best for me (which would give a slight edge to the DFW flight, not least because of the later time of arrival which, among other things, should see immigration not quite as bad as for the early morning bank of European arrivals).

Am I correct or is it possible to form a reasonably informed guess on what will most probably be flown on any of the three routes?
