DSA (Robin Hood Airport (that is it's real name not just a comment on it's attitude to ancillary charges)) and EMA (East Midlands Airport) now have BA code shares to and from Dublin being flown by Aer Lingus Regional (operated by Stobart Air.

Stobart Air fly Turboprop ATR aircraft which could be quite fun, and open up EI's westward network.

I think this also suggests that EI's arrangement with Stobart Air will carry on after the merger.

BA code shares prices from around £80 one way.
