Welcome chrisslaterwalker
Welcome chrisslaterwalker to Flyertalk and we particularly welcome you to the British Airways board. Congratulations on your CW experience, to which I am sure you are really looking forward. Please feel free to continue posting here, it's great to see new faces. Welcome on board!
Now this, notoriously, is the route I'm destined never to fly, so I'm not a lot of use here. Other than that it will be flatbed for certain. If you are a single person who likes the window, have a look a the seats that go into the bulkheads since they also aisle seats in a way. If you are going as a couple then consider the middle seats, particularly overnight. Have a good wander through the Dashboard, there are all sorts of nuggets squirrelled away there.
