Yes, that is correct. YVR is also supposed to get SS3 at some time in 2019, I believe. Neither will help the OP in this situation since they are looking to travel in March (although if they are returning on or after 1 April then SAN would be a lie-flat option). Finally, I forgot about NRT-SEA, which is starting March 31.
