CO to DUB-EWR will probably go 2 daily. IAH is a very longshot, due to their lack of aircraft, and they could use the aircraft needed for that route on another route, most likely to Asia. SNN-EWR will also stay. However, who knows what will happen; 737's? 757's? daily? who knows?
AA will probably stay daily/ 5weekly (winter) DUB-ORD, and probably seasonal BOS-SNN
DL will probably go daily DUB-ATL, and I dont know what the loads are like for DUB-SNN-JFK. The SNN-ATL apparently isnt performing that well
US Airways will probably go year round DUB-PHL, and seasonal SNN-PHL
NW to Detroit is interesting. Its a long flight for a 757, and they havent go the best of reputation in the states! We'll see what happens with them!
