No more problems than usual with the RJ's. Sometimes you have to substitute for a line casualty and you grab whats available.
We did have a problem, along with many others, regarding rehydrated de-icing fluid from somewhere in Europe. That has now been addressed and with luck shouldn't reccur. Especially as it put 8 RJ's off-line at one point!
However, thinks are back to what passes as normal in the Airline world.
