Seperate Seating

Dear British Airways, <br> We flew back from Durban to Johannesburg yesterday using British Airways. The was a slight delay, but that's not the issue. Our flight was supposed to depart at 17:55pm. We checked in 16:30pm. We checked in as a family of 3, (my husband, my daughter & I). On the plan, we realised that we were not all seated together, I specifically asked at check in if my daughter could have the window seat. On the plane, we realised that the window seats were taken, I sat in the middle between a another person & out my daughter in the isle seat, my husband was booked on a another seat. The person , an adult , wasn't kind enough to allow my daughter to at least sit by the window. Anyways ... such chaos ... but we got to Johannesburg fine. <br> <br> Please can your checking in staff allow families to sit together. <br> <br> Very disappointed!!
