This is in response to a comment by BNE from Australia, to my first thread which is now in the non-aviation forum, re Delta pulling service out of YVR.
This was back in 1998. However, I believe in 2003, they resumed with a seasonal ATL YVR flight during the summer, due to Alaska cruise ship traffic. I thought it exremely odd, as the reason given for them discontinuing service at YVR, was due to the fact that most of the demand was leisure passengers, not business travellers, therefore the yield was too low.
At any rate, I understand that they now have a year-round service to either ATL or SLC, or both, and for sure Skywest, using the code DL does have daily scheduled service YVR SLC. I haven't checked their schedule for a long time, though, so that is where you would get the facts.
At one time, during the summer, Delta had up to 8 flights a day out of Vancouver, including nonstops to Cincinnatti and ATL, and couple to SLC, 2 or 3 to LAX, 1 to SFO and 1 to PDX. The latter was full a good portion of the time, to connect with the numerous flights from PDX to Asia. I also understand they are largely out of the Asia market now, maybe someone could enlighten me on that?
