Using ITA to look for UA award and upgrades now only shows direct flights, connections are no longer displayed.

For example DEN - MUC displays only the one direct flight a day and none of the connections at ORD or IAD. DEN - BRU shows no flights because only connections are available.

Actually in some cases this is a desirable feature, but when looking for all possible routings on a given day it is a serious disadvantage.
