The other thing about the ER, that is becoming apparent everywhere is that it is a jack of all trades. There will probably be some SEA-NRT-HNL-LAX sort of trips, and maybe a few other Pacific adventures, but you can bet there will be plenty of 75 trips to ATL, MCO, etc... The 330 seems like it is a pure international bird, and bidding it is a virtual guarantee that you'll be avoiding the 2 and 3 day domestic trips.
