My wife and I use 1A/B all the time if it is available. Otherwise it's 2A/B or 3A/B.

Tomorrow it's 3D/E which is our fallback if we can't score the left side, which is full, probably all FlyerTalkers who read this thread.......heh. We were stuck in 6K/L two weeks ago and didn't like the back row of the J cabin at all. Far too noisy.

The route we regularily fly uses both boarding doors for J, which is handy.
