The replacement of Moscow by MAN has been mooted since 2014 and was talked of by enthusiats and others in Houston on my visits there in 2014. A Scoot 787 would have damaged the SIA group's profitability on the route, not only because of a lower yield but also due to a lack of freight capacity compared to the current 777 capacity so it was unlikely that the Scoot option would have occurred. Also the nearest Scoot gets to MAN is Saudi Arabia with no flights outside Asia/Australasia and none planned. With the crew deals it has, it will be sometime yet before the white and yellow diagonals are seen in Europe.
