Yep, EK is one. But good luck for F Class on that! DL reps have to manually check each flight and date directly with EK, so you will be on the phone for along time. I tried every day for three months and could not find one day out for a trip that was 10 months away. EK just does not give DL the inventory and they sell so many anyhow.

As of today, a DL rep confirmed that Air France, Korean, Virgin, and South African are out of on their way out.
