QR 787
"And Qatar Airways will make London its first destination outside of the Gulf to see a daily route with the aircraft. " - quote taken from more than one travel website.
You can read this in two ways - London will be the first 787 destination outside the Gulf,( i.e. it won't be MAN), or the first to see a daily 787 service - i.e. MAN might be first destination outside the Gulf but 787s mixed with A330s at first.
Who knows? It would be nice for MAN to be the first, but inevitably airlines will tend to launch high-profile events at high-profile places. London will grab more attention than Manchester. I'm sure DOH-MAN will see a 787 fairly soon, it will give QR something to pitch against Emirates' A380.
