It looks like HU has published those cheap fares round-trip LAX-PEK for 2019.

How long does EF usually take to update with new or updated fares published? On matrix I can price a $2214 LAX-CKG-PEK (for example) round trip using fare basis ICLRGUSF next year, and the fare rules on matrix say that it's valid Jan 1 - Apr 24. But when I look it up on EF it's still showing that the fare expires 12/31.
