Hi, just had confirmation of a change of flight time for first leg of our journey from NCL which means we can no longer catch our connection at LHR. Indead, we can not even connect with the next flight as we have a terminal change as next available flight is with AA ( we were BA all the way originally) from T4. We at best can fly 4 hours after our original time which means arriving in Boston a lot later than planned. I am furious! We have also paid £60to book seats! Help Can we demand compensation/ upgrade or do we just have to grin and bear it?
