BA CityFlyer Embraer 170 G-LCYF operated an Edinburgh – Malaga charter rotation early this morning as BA4517/BA4518. However BA4518 diverted to Glasgow due to weather at Edinburgh. The aircraft then positioned Glasgow – London City as BA9750 in order to operate the delayed BA8710 London City – Edinburgh where it was stopped for maintenance. As a result BA8707 Edinburgh – London City was cancelled.
