I've got a city-to-city flight in the summer as part of a paid RTW. The flight I'm booked on is showing as op by JAL.

Since I'll probably be making further changes to the RTW, and the change fee is $100 per transaction, I can choose to move to a KE-operated flight for no extra cost.

As per OK+ rules, I'll still get my miles if I keep the JL flight, so that's not a consideration.

I'm in business class.

Shall I try and keep the JL flight, change to a KE one or just focus on timings etc?
