Assuming the majority of AF and KE passengers are not going to make the trek over to T4, from a departures standpoint we’re looking at:
- LA: 10x weekly Lima, daily SCL, daily GRU
- KL: 2x daily AMS
And the one with a significant number of flights (but also their own lounge):
- VS: up to 7x daily LHR
What they could have done is not integrated the Delta One check-in with partners (make check-in Delta Only and have other airlines check-in at their own counters). Partners can still access the lounge but they are not fed directly. Would significantly decrease lounge loads, especially the 8x daily VS pax that is fed straight into the lounge when they have their own.
