With tiny leg space on long flights, an infant on your lap can leave you with a lot of aches and pains. Select airlines—like Air New Zealand—however, are trying to make flights more comfortable for families.

Most US airlines instruct parents to keep an infant on their lap without a seat belt. Air New Zealand, on the other hand, plans to include infant harness and belts on all of its Boeing 777 and 787-9 long flights. This arrangement—complimentary in the economic coach—allows passengers to recline flat down with their child, without paying for a business- or first-class seat. The harness comes in three sizes and can hold a baby up to 40 pounds (approx. 18 kgs). A bassinet-like baby pod that allows infants to sleep flat on their back has also been introduced.

Another airline looking out for comfortable long hauls is the Kazakh carrier Air Astana, which services Astana, London, Frankfurt and Paris. Its Economy Sleeper lets passengers have an entire row with the armrests folded up, with a mattress, pillow and duvet provided. We’re unsure of how comfortable it’d be for an adult to sleep with their baby within this arrangement, though. Air New Zealand isn’t far behind here—its Economy Skycouch offers raisable leg rests for a larger sleeping space.
