I apologize, I'm pretty sure this has been discussed, but I have been searching for 2 days now but couldn't find the right thread with the answer.

I am trying to get tickets for family for a MNL-ATL trip. I was looking for an alternative to direct booking (to save $1000) and I thought of this.

1. Have them book a KE revenue flight to LAX.
2. Book a DL award from LAX to ATL for them.

1. My questions are, would the inter-airline check-in benefit work?
2. How do they do this, would they just present the DL reservation to the KE desk?
3. Are missed connections and sending luggage to the final destination taken cared of if I do this?

Thanks guys.
