I'm off from London City to Dublin next week and always make sure the office books me on the 146/RJ from Cityjet instead of the competing BA Embraer jet. It's nice to be back in a UK-built airliner. And I think if it wasn't for the 146 bringing jet service to LCY, they would not have got out of the commercial hole the airport was in shortly after opening. There aren't as many operating from there as previously, but you can still see a good number on the ramp each day.
I think that, Airbus apart, it was second only to the Viscount in mainstream airliner sales from any European manufacturer, and if they had continued with the RJX would likely have overtaken the Viscount's numbers as well.
