Still weighing pros and cons and with US the cons keep piling up

The other thing I realized is that the elite mileage bonus is less than United for levels under Chairman and that I get full elite UA bonus miles even on US flights.
Im really going to ABE (Allentown) so its looking like my best bet is outbound redeye SEA-IAD-ABE and return ABE-ORD-SEA on UA. The cons are the Saab and CRJ-200 in and out of ABE and getting into ABE at 9:45a despite redeying.
So I think I have bagged even asking US for a match.
