Won’t all of the inbound 737-900s from Indonesia add a lot of short-haul flying due to their uncommon layouts (e.g., lack of ovens, etc.)? So, conceivably a lot more 500 mile-radius flights out of ATL that the MD88s used to fly?

Personally, if I were based out of SLC, SEA or LGA, I wouldn’t waste my time on the A320 or 737NG when I could fly the mighty A220-100/300 instead! At least the proposed A220-300 rates look pretty good.
