I booked a Eurowings intra-Europe flight as a UA award last week (6 days ago). I immediately received an eTicket and confirmation from UA, as well as a Eurowings PNR separate from the UA PNR. The reservation shows as "ticketed" on United.com.

However, if I enter the Eurowings PNR on Eurowings.com, I get the error "No booking could be found in the system that matches your input data."

If I enter that PNR on lh.com, I get the error "Your booking can only be serviced if the flight tickets are issued and the payment is confirmed. Please contact your original booking office or your Service Center for more information." This is a different error from the one displayed if you enter a random PNR ("Unfortunately, your booking cannot be displayed.")

So I'm thinking there could be a problem with the reservation. If I'm right, what's my best contact at UA? And will I be able to convince them there's a problem, if everything looks ok on the UA end?
