So do easyJets airbii apparently. Of course, the minimum warmup and cooldown times have to be observed i would think. Recently heard from a mate in Lufthansa that they have SOPs for that on the A320 as well, but that the single engine taxi out is apparently rather rare if done at all. And of course the NEO with its long startup time makes things even more difficult.
