Red,
You still have a hard time understanding some of these concepts. Yes, DL has a lot of codeshare partners. Just like SWA has one (Volaris), and almost had another, until Westjet pulled out of the deal. SWA had ATA also flying 738s to Hawaii from OAK, until they went BK. Most of the DL codeshares are airlines that fly within their OWN countries. Delta cannot fly WITHIN China, or Australia. That's cabotage. But, those airlines can gather up passengers from cities that Delta does not have rights to, and can bring them to the ones that DL does. Delta doesn't go to Shenzen, but China Eastern can fly people from there to Hong Kong, and then Delta takes them to Detroit. Virgin Australia can take people from The Gold Coast in Australia to Sydney, and the Delta can take them to LA.
The difference with that and the SWA/Volaris code share is that SWA doesn't go to Mexico at all (Airtran does, but no SOC yet), and Volaris was flying to the USA (OAK and MDW) and taking passengers to and from Mexico. SWA management maybe didn't trust you to fly there, maybe they thought the VNAV and Autothrottle addition for you guys could cause an overload. You may try to counter with the Saudi thing, which you might claim is a codeshare. No, it was a ticket agreement, not a codeshare at all. Southwest probably has many ticketing agreements with other airlines.
Now let's talk about scope and RJs. There is no doubt there is a large abundance of RJs at Delta. But, that number is coming down, almost as fast as a Corndog 737 with a roof coming undone. 50 seaters are going away quick, and the limit on 70/76 seaters is almost at it's contractual peak. It won't go higher. The overall numbers are decreasing.
And most of the extra bigger RJs came the way of BK court. I hope the UAL and CAL guys can see that, and also do NOT sign off on something like that. I think they won't, and their current stance on RJs is good---they seem to be standing firm on what they want. That will be good for all of us.
So come on Red, try to debate me. You can't. When you figure out how INTL codeshares work, get back to me. When you get checked out to Mexico, thank Ty Webb.
Bye Bye---General Lee
