Didn't see this mentioned yet but DL just rolled out a few real improvements to the partner/code-share experience - with ability to check-in for partner-operated flights on the Delta app or at delta.com, as well as the ability to choose seats on some partner-operated flights directly through the Delta App or on delta.com...

- Check-in is now available through Delta digital channels on AF, KL and VS-operated flights
- We can also now select seats on AF, KL, VS, AM, KE and WS-operated flights! (this to me is HUGE) through delta.com or FlyDelta App...It looks like you can even do it on the short-haul intra-Europe flights on KL and AF...and in all classes of service. I have an AF-operated flight this month and was able to change my seat online through the DL app today...
