Hallo Vanessa
Since the flight is tomorrow morning will deal with it at the airport if need be.I re checked the flight all day until a row of three together came up briefly however there is no garantee it will still be so when I get there in the morning. I don't know if it is just me but we have encountered this seat swap on just about every flight the last 3 years - iguess thats why this chips me off so much nowdays sicne the LH computer seems to have us on his seat bump list.
Maybe this is something LH could help with. One can already mention ones preferance in the M&M account. be it windo / aisle etc. It might be a good thing to be able to advance such a listing to link bookings and reasons why such seating requests exist. Making the computer aware of seats that may not be a good idea to change.
