Nowhere does it say that they are launching EWR-SFO/SEA/SAN. It says that there will be a total of 22 flights between JFK/EWR-LAX/SFO/SEA/SAN.
EWR-SEA/SAN/SFO are not happening.
Exactly. Nor'Easta (in post #8) completely misread that paragraph of the press release (and the JetNet item). Didn't place the hyphen and the dashes in the correct place (you, of course, did).
