Traveling with 4 children we thought we had seats together when we booked. Got to the off airport check in facility and found out two of our seats were 8 rows apart. The staff said it happens all the time with change of aircraft and if you don't check you could be out of luck.
The staff was nice enough to call the airline and get us all together so I would recommend you check your seats again before heading to the airport.
