Just a data point: Two QF OWEs were permitted access to NRT F lounges on 4 Jan before MH71.
Main lounge at ~3:30pm was probably 30-40% full. Angels gave us the "we're letting you in this time but can't guarantee we will next time" speech.
Wandered over to the satellite at ~6:30pm until closure at 7:30pm which was virtually empty. No speech.
For those who appreciate whisky, they had Akkeshi Newborn Foundations 2 in the main lounge and Yamazaki NAS in the satellite. Both also had Hibiki Blenders. Also, here's the sushi schedule for the next few weeks.
