I commute from DAL so I'm not totally up to speed on WA. But I know when we only had COEX bases (IAH, EWR, CLE) a lot of SEA commuters were based in EWR. It sounds crazy to me, too. But we have a JS agreement with EVA (I think we are the only ones with an agreement) that was an almost guaranteed ride home. Now that we have the LAX and ONT bases, I'd think they be fairly easy.
