They have one ACT for their A321neos. Ditto Delta. I think HAL has two, but don't quote me, as they fly SLC-HNL. I was sceptical that UA could use a 200 seat A321neo without any ACT to make it on flights with takeoff to landing longer than five hours year round. If UA flies SFO-HNL/KOA/OGG year round on a A321neo, then colour me pleasantly surprised.
