Nice report! Must say that the BusinessFirst product looks fine, and I wouldn't mind trying it sometime.
Though I can't agree on SK's Economy product making it anywhere near the top. Ancient loop-IFE (i.e non AVOD), only a few limited servings of alcohol, and the fact that you have to pay for your sodas, juice and snacks served in-between the meals. I would might consider it even falling short of United's Economy.
