Would suggest a change to the master "Best Seat" posting above.

I flew AC575 YUL-LAS yesterday and unfortunately, the usual A319 was replaced by an A320 (seasonal change?). While 1AC are still preferred seats, 1DF appeared to have the same legroom. But none of those seats are even close to the legroom in 2AC on the A319, where I can use my roller carry-on as a foot-rest.

The only negative to the ton of extra leg room in 2AC on the 319 might be the distance to the AVOD system. Then again, since I bring my own and with the map feature now in its 3rd year of non-functionality, it's not a big negative to me.
