There is no Justification For Your Complaint.
You can’t possibly claim that going on vacation with your family is easy. Even the smallest piece of information that you provide to parents can have a significant impact on the lives that their children lead. This FA recommends installing car seats in the rear seats of the vehicle. Are you in any way taken aback by this information?
It is impossible for anyone to transport that in their carry-on. The use of the car seat on an airplane or when arriving in a new country may be the best option for preventing tantrums and making the trip more enjoyable for both the parents and the children. Since children do not like change, using the car seat in these situations may be the best option.
