TÜV Rheinland researched the risks for a child held on the parent's lap, and found the results were so alarming that they now advise that a separate seat is booked for any child; and that the child is safely secured in a correctly installed car seat. The safety test made by TÜV certifies that KIDDY car seats "with due consideration to specific requirements of aircraft, represent an increase in safety" for a child on board an aircraft.
The KIDDY Phoenixfix Pro 2, Guardian Pro 2, Guardianfix Pro 2 and Smartfix are all TÜV aircraft approved Group 1/2/3 car seats. The KIDDY Evolution Pro 2 infant carrier is also TÜV certified and can be strapped in using the aircraft seat belt. Taking your own car seat on board an aircraft also means that there is
no requirement to rent an unknown car seat at your destination. Your
child will be safely secured into a quality car seat, which you know
its history and is also correct for their age and height.
We strongly suggest that you inform the airline of your intention to
use a child car seat on board the flight, at the time you make your
booking, or before flying. The airline companies will have their own
information on car seat use on their websites. Please note: It may
be necessary to use a belt shortener to secure the car seat on some
flights. These are available as an optional accessory for KIDDY.
