With GREAT difficulty managed to book one ticket and now can't get the other booked. The Google flights link to UA doesn't pull up the flights and UA just says to see the error message, of which there is none, and won't return any flights at all. Best I can do is to get an outbound to come up but even that I can't get for the last 30 minutes.

And now no other sites will find the flights. What have they done??????
