Booked a Swiss A330-300 Flight with my wife and infant (in-arms) in Business. 6D and 6G were already booked for someone else also with a infant.
The call center had to send our request off to some group in Switzerland to have seats assigned for my wife and I. Apparently only row 6 is acceptable for infant-in-arms. Someone suggested that this is because row 6 is the only one without airbags in the seat belt.
We ended up in 6K and 8K since neither my wife or I have any status right now. 8K was the nearest available seat to 6K.
The call center suggested that I could ask at the airport about switching to 7G or 7K but I doubt very much that the seats would be open by that point.
