I think that AS
has expanded to large O&D markets from SEA
first and foremost - many of those happened to be AA
previously flew SEA
3-4x daily, and when they dropped the route with their closure of the DFW
hub, there was a void. AS
filled the void, in addition to AA
putting 757's on the route and adding more frequencies.
is a high O&D market from SEA
, that can support multiple flights. Even with AA
, and AS
, loads and yields are still high. Don't forget that SEA
's hub, and many of these passengers are connecting from smaller cities in the Northwest.
is a route that was previously flown by NW
saw an opportunity with these carriers reducing frequencies (and subsequently dropping the flights all together). The route connects two technology centers and has decent yields and loads. AS
hub provides feed to make it successful.
is a route that was dormant for a few years since AA
cut their MIA
saw an opportunity and has done somewhat well with the route.
I would imagine that AS
because a) there was already plenty of competition on SEA
, and b) they do codeshare with CO
on some flights, and CO
offers more connections out of EWR
than does AA
out of JFK
. Plus, the route caters more to people that have NYC as a final destination, and EWR
is more convenient to Manhattan than is JFK
I think by and large, AS
has picked new markets based on O&D and connections from their SEA
hub. By coincidence, many of these have been AA
hubs but I don't believe that was the overriding factor. In fact, in the case of DFW
won't let AS
codeshare on connecting flights because they're upset AS
started the service.
