Hi - new to Flyertalk and looking for some help with a miles redemption.

I am going from NYC to Tokyo next September / October for 2 weeks and would love to fly business.

I have c. 110k Amex points, 120k Chase Rewards, 150k Delta and 220k British Airways points but have never used any of them to book flights.

There seems to be a lot of options (ANA, JAL, United) for airlines but I am not sure on where to prioritize sending my miles to book? I would like to avoid getting stuck on the dreaded waitlist!

Can anyone help? Thanks!
