LAX for DL was a result of the Western deal and was and has been a boon for them.

thank you for demonstrating your good sense, tech.
I can't go back before 2000 on revenue data but DL's revenue share at LAX since 2000 has grown from 11% to 19% and is nearly as much as UA before the merger.
For California as a whole, DL's revenue share went from 8% to 11%.
While DL doesn't do as much of the north-south flying up and down the west coast that WA did, including LAX-Mexico, it obtains much of that access right now through the AS codeshare which is shared with AA. Despite the loss of much of that flying - and DL is growing in LAX-SFO and LAX-SFO again - DL still has a larger share of the LAX market than it has ever had, partly as a result of the residual effect of the WA merger and partly a result of the NW merger. Either way, DL still has nearly 1/5 of a highly competitive market that has a number of low fare carriers in it and is still within a couple of percent of any network carrier.
