I agree that Express will probably shut down. But I called US reservations and was told that the Beechcrafts will be flying because they have no F/A. (So what...the Express F/As are under a different contract.)
So I emailed Commutair (one of the US Express affiliates here in the northeast) and was told they were not sure. But US handles their ground work, so I think if US is shutdown that Express won't be running.
Why isn't US straightforward about this and make a decision about whether Express will be running? On the same token, why don't they just settle the contract now, before they lose too many bookings.
