G-SAJC has done the GLA-SYY flight LM476 today. It does not appear to have been out since the same flight on Monday last. An SF34 did two of the flights and an SB20 did yesterday's plus all the evening flights that the jet was pencilled in for.
The article featured on the Stornoway Gazette website did not appear in this weeks printed paper either, so it's hard to say whether last Monday was the inaugural flight or if there was another flight the previous Monday, 7th Jan.
