Seat assignments may be back but they removed something else awhile ago that would be useful. I often put a 7-day hold on reservations. When I open a reservation that is on hold it no longer displays the price at which the hold was placed. It used to show that. The only way to see the price is to click the "Purchase Now" button. I continue to shop during the 7-day hold period and this is just an extra new step to the comparison shopping exercise.

United giveth and United taketh away.
