I happily got an oppurtunity to change my familys seats in the Mid-J CW (747) from LD (row 18 and 19) to UD (row 61) on our flight tomorrow (BA0271) as new available seats showed up during check-in. (Since we start our flight from OSL, with connecting flight from LHR-LAS, we got to check in for the whole flight already now) What worries me is that when I enter "Manage My Booking", our old seats are still showing, but shows as available on the seatmap. My check-in-confirmation showed my new delightful UD-seats.... What should I rely on, the info on Manage My Booking, or the Check-in-confirmation? As I wrote in an previous post, this is our very first (and probably) CW-flight, so I am worried about most things, and wanting everything to be as smooth as possible ;-)
