Nope. You only get one baby item and no extra weight for baby in your suitcase like other airlines I’ve flown do. We had to use one suitcase for a travel cot and took the pram as the baby item. I imagine you’ll have to pay for additional special luggage or purchase a seat for the car seat. Very annoying
Might be able to check in the car seat (in a travel bag) as an additional luggage item as long as it’s until 20kg c
