Thanks All
Thanks all for your posts
Outbound flight leaves Manchester in the afternoon (A380 Left window seat). Flight to Kolkata (A330 Left window seat) is in the night 3am departure.
I have internal India flights and then back via Mumbai - Dubai A330 and A330 to Manchester.. I guess I will be too tired to look out of the window then :-)
Biz seats so the A330 should be okay as well as the A380.
