Plain and Simple
I will believe it when I see it.
The talks about GUM-LAX have been in effect for several years. While it is true that runway length was an issue, GAA have fixed it. This particular topic has been an overkill in CS. The biggest fear about opening GUM-LAX is that should this route open up, HNL's volume will drop. And to this very day, that is the response that CS management is replying with the same as it was several, several years ago, when we were flying 74's.
Also since someone else brought in the idea of an EWR flight, statistics show that there is not much incoming/outgoing traffic for EWR area. Most traffic into GUM is from the midwest and west coast USA. That route will be less than likely Only because NRT has both IAH and EWR flights. At one point it was an idea in our MGMT meetings with CS (FYI, former mgmt here) but when the numbers were pulled, it showed that an GUM-EWR would not benefit the company .CS's focus is on volume for the obvious reasons.
