The AAIU have published a report today on the incident that happened at SNN Airport with an Aer Lingus Regional aircraft (EI-SLM) in July 2011.

Some routes still not on sale it would seem, BHX-DUB and BHX-NOC not on sale as of yet. The ATR42's still hanging on for winter! From what I know 42's have been at SNN over the quieter months this winter.
It's just the Cork & SNN routes that are on sale. My guess is NOC-BHX will be operated by a DUB based aircraft. The DUB schedule hasn't been finalised.
SNN had an ATR72 based from the end of October until the 7th of January this year. An ATR42 was based in Shannon from the 8th of January until the end of the W12/13 season. EHH has been in and out SNN since the start of the S13 season. It is based in SNN now.
