This maybe to late, but I´ll post it anyway.
We just flew with EA from Addis to Frankfurt, with our 1,5 year old daughter. She is 83 cm and we got a bassinet for her. It was a little to short for laying inside outstretched (my guess is that the bassinet is just ca. 78 cm), but even so she still slept in it and loved sitting in it. Weight wise its totally fine til I think 16 kg. So it works, although it´s not the most comfortable for children this age.
