Terrible! Brought kids to check as UMs 2.5 hours before their long-distance flight from London to Jakarta.. Was made by rude staff to write out UM information in triplicate despite the kids already having UM forms; was then told to take the kids away and bring them back in one hour; was then informed they could not under any circumstances be taken into the care of the airline until 60 minutes before the flight - despite the fact that one of their own staff had said 90 minutes - and despite the fact that I needed to be elsewhere checking in other children.
