EU infant seat belt regulations.
Last week my 1 year old granddaughter and her parents made flights to and from the UK to another EU country.
On the return journey my son was not handed the seatbelt to secure his daughter until the cabin crew had completed their safety briefeing. By this time the aircraft had taxiied quite a distance and the "fasten seatbelts" sign had been on for some time.
Is this permissible. Surely if the seatbelt sign is on all passengers must have their seatbelts fastened and secured, including any restraints required for infants.
Does anyone know if regulations cover this point and, if so, what they say?
(I am only asking so that if the rules require it my family can ask the cabin crew to provide the infant restraint in good time in future.)
