Austrian is planning to restart 5-time-weekly services to IAD, although no longer routing through ZRH in co-operation with SR. They are also planning to start daily ORD service, so these are most likely there to feed United's network. My step-mother (who's Austrian), has a sister who works for OS, and from what I've heard, OS seems to be a very good airline, and if they ever fly non-stop out of Boston, I hope to fly them.
