HU has apparently suspended its twice weekly service to OKA (its only Japan service) "for political reasons". There's no announcement yet on their website, but this is according to their reservations department - I was supposed to be flying with them this weekend. The suspension began mid-Sept and according to EF looks indefinite. CA is still operating its twice weekly service.

I'm a bit unhappy that HU didn't notify me of the cancellation immediately. I only noticed when checking loads on EF. They have offered to rebook on another airline though.
