Following its diversion on 24th July, BA CityFlyer Embraer 190 G-LCYN positioned London Southend – London City as BA9750 this morning then returned to service operating BA8702 London City – Edinburgh. The aircraft then operated BA2345 Edinburgh – Florence, however this service diverted to Pisa due to weather at Florence. The aircraft positioned Florence – Edinburgh late at night as BA9755. As a result BA2344 Florence – Edinburgh was cancelled.
