UA and NW in Dublin

Ok SFO is a possiblity for UA,but the fact LAX has been running now since 1999 with EI,and it still hasnt matured into a daily service doesnt look too good for the future,especially if you look at SFO which is in a very similar part of the world & can develop a daily service in what 6 months?, i would say the LA route could be dropped in favour of an increase to SFO.

SFO will be daily next summer and LAX 4 weekly so the demand is quite high, and UA would have the bonus of feed from domestic flights into SFO, but as mentioned above capacity is and issue and a SFO-DUB return rotation requires a decent amount of capacity, IE it takes a good 23 hours so 1 aircraft cant do a daily flight on its own.

IAD already covered by EI and not their hottest T/A route to say the least.

NW from DTW a possibility but what do they offer that CO,US, AA and AC dont already offer during the summer?

Yes rumours at best,

NW came very close last summer,along with MAN i believe,but something spooked em good very close to the start of last summer!

As for UA,i dont think they’re too bothered to be honest,no real competition from Aer Lingus,ok EI do SFO but with thats not even a daily service(not yet anyway) it doesnt really warrant another carrier on the route,same situation for years on the LAX route,EI cant even justify a daily themselves,so the demand is there,just not that big

Cant see UA doing a run from IAD either,same story is not even daily with EI.

Whilst Northwest have been ramping up their international operations lately United are in the same situation as most American carriers these days in having a huge lack of capacity and being constrained on any expansion plans they might ideally wish for.

Ive heard these rumours for years now, possibly true but I wouldnt hold my breath!
