In addition to the 2 hour delay of JL16 to LAX, JL6 to JFK is also about 6 hours late today because of issues getting the aircraft ready in time. (使用する飛行機の手配のため.) I don't know if this is more knock-on effects of the flight 4 diversion or if it's something else.
It feels like the reliability of JL's A35K fleet is terrible. It's been a year and a half since introduction (of a type that's been in service with other airlines for several years already) and they're still having issues?
