Stumbled across this on Etihad's site and thought it was quite good, as I don't often see cheap business class out of CPH:
- book by 04/01/17, travel before 21/06/17
- books into Z
- EY doesn't fly out of CPH, so you'd likely fly first leg on SK, SN or AB, but from then on it's EY.
- book via EY site, but can even lower using OTA's
- other eastern destinations available (eg India, Thailand, Sri Lanka) for slightly more.
