Honestly, there's too much in flux now to make an intelligent decision. The inability to use Russian airspace has had a tremendous negative impact for the base. India (Delhi/Mumbai) flying, which was a staple and expanding (Bangalore?) went away. Even if China opens up, Hong Kong will be undoable without going polar and Beijing and Shanghai will each take about an hour longer than normal. Right now, over a quarter of the base is on reserve and close to half of the reserve days are converted to short calls. trip lengths have gone from almost exclusively 2-4 days recently to a lot of five and six day trips being added in. it's possible those longer trips, which seem to include a lot of flying for other bases, might be reduced if/when Russian airspace overflight comes back.
