EY CAI - NRT in F (First) for $2499 usd
Etihad CAI - TYO in F for $2499 usd. Completely wide open open on google flights. Not sure if it been around for while but it was useful for a trip of mine so thought i would post. I have had good experiences on EY 787 first class, although its not the apartments its still as good as most first class cabins.
