My in-laws have just returned from their annual summer break. On the return flight they found that ther pre-boooked seats were in fact allocated across the aisle from each other. Although apparantly this is seen as being "together", they were not happy about it. CC very kindly re-seated them where space was available which happened to be by the overwing emergency exit. 2nd CC came along and asked them to pay more money as extra leg room seats cost more!!
