Stop by Love Field sometime, then tell me if you still think WN
's presence at DAL
is "almost nil." Yes, they are limited by the Wright Amendment to intra-Texas, neighboring states, and a few other states, but it's still a very significant operation--not to mention their birthplace and still the location of their headquarters.
Ditto with DL
. Sure, it's dwarfed by AA
's operation there, but there's no question that it's a hub nonetheless. And your previous comment that SEA
"needs a major" is not quite right either--AS may not be the largest airline, but its hub at SEA
is more than many U.S. cities can ever hope for, both in terms of size and quality of service.
