Thanks for the info, this is what I've got to choose from:
EK16 I've taken 1k as that is the only window seat available.
EK770 No window seats left so I've been assigned 1b. All 4 middle seats are available as is 2b - what shall I do, do I take the middle to avoid the cold?
EK771 This one's busy! No window seats, been assigned 1b again. Row 2 middle seats available as are 2b and 2 further aisle window seats??
EK3 This must be the one with the Suites, been assigned 1k but the two Row 2 window suites are available - are they better?
