Hi i have finally got to a few hours before OLCI opens and loads of seats have becam avilable!

Does any one know which is better, one of the seats in isles 21-23, these seam like they are right next to the PE so wondering if they will be in the bubble? ?| ?|
Or i can have one of the few pairs of seats, so far i have gone for 62A and B, as it is just me and the mrs.

Have i made the best choice here?

Hi, the two at the back are good, but you may have people waiting for the toilet next to your seat. The other seats you refer to won't be in the bubble, but closer to the front, which will be quieter and better for getting off the plane and immigration queues.

got seats 51a and b, hope they worth the extra £60??
