It is difficult to comment without an actual example. KE and DL coordinate on fares between US and parts of Asia (but not China) and generally have identical fare filings. But bucket inventory may not be the same on the same flights depending on the marketing carrier.
As an example, DL and KE have matching $325 fares on SEA-ICN (XLG0ZNMD on DL and QLG0ZRMD on KE), as well as matching $400 fares (TLG0ZNMD on DL and ULG0ZRMD on KE). In the roundtrip example below, KE has Q and U bucket open on the flights when KE marketed, while DL only has T bucket inventory availability on both outbound and return flights when DL marketed. If DL had lower X bucket open on outbound flight, the total roundtrip prices would be the same (due to DL's $325 X fare matching KE's $325 Q fare),
Same flights with DL marketing and bucket inventory.
