I went to the new united.com (old continental.com) to book flights to Oslo from IAD in December--realizing that I can't find anything about upgrading now but at least I can get a W fare. So I entered leaving late evening and got a full list of all connections during the day and finally found the 9:56 departure from IAD to FRA with a connection. Selected that flight and then looked for the requested early morning return about 5 days later. The only option I got (tried this three times) was a late night departure involving an overnight stay in FRA.
Anyone in charge of the website?
