I will be travelling with two infants in Y on an LH A330 in February. They have assigned our travelling party (myself, husband, Mom and two infants) in the middle bulkhead row 29. In my previous travelling experiences, there is only one additional oxygen mask per row of seats. Two seats, three oxygen masks, etc.

Given that there are four seats in the bulkhead, and the three of us are seated together (with 5 people), will they seat someone in that fourth seat? If they do, are there more masks in the bulkhead because LH knows that they always sit lap infants in that row, so they added extra? Or is it the same as other airlines with only one extra?

Trying to avoid major seat shuffling after we get on the plane.
