Hi -
About 3 years ago I learned a secret - that Delta partners had to honor the delta mileage chart for 1st class tickets if they were available. As a result, I got 2 first class tickets to/from Thailand via China Southern - each for 60,000 Skymiles.

I am looking to potentially re-create that same experience from the US to Japan. I will be using American Express Rewards points - so Delta isnt a requirement but I will be leaving from Atlanta or LA, so...

Questions:

a. Is this still possible via Delta skymiles.

b. What tool is there to find available seats by partner airline?

c. Which airlines do you think would have the best availability that go nonstop from either Atlanta or the West Coast to Tokyo?

Thanks.
