Eligibility depends on the airline and aircraft
Airlines set their own maximum weight, length or age for bassinets, and the equipment differs between fleets. A baby who qualifies on one carrier may be too large on another. Some aircraft have only a handful of positions. Check the operating airline’s current rule for the exact flight rather than relying on advice from another route.
Codeshares deserve particular care. The airline that sold the ticket may not be the airline operating the aircraft, and it is the operating carrier’s seat map and bassinet procedure that matter.
Request early, then verify again
Some carriers let parents reserve bassinet positions in advance; others record a request and assign the equipment later. Contact the airline after booking if the website is unclear. Recheck after schedule or aircraft changes, because a seat that originally had a bassinet fitting may disappear when the equipment type changes.
At the airport, ask again if the request is important. Cabin crew will make the final decision about safe use, and operational changes can still affect availability.
Bulkhead seats have their own compromises
Bassinets are normally mounted on a bulkhead, so there is no seat in front under which to store a bag. During takeoff, landing and sometimes turbulence, cabin baggage must be in the overhead locker. Parents should therefore keep a small pouch of immediately useful items easy to retrieve once the seat-belt sign is off.
Bulkhead armrests may also be fixed because tray tables or screens are stored inside them. Depending on the aircraft, that can make the seat feel narrower than a standard row.
A bassinet is not a guaranteed bed for the whole flight
Crew can require the baby to be removed and held or secured according to airline procedure whenever turbulence makes bassinet use unsafe. A child may also refuse to sleep in an unfamiliar cot. Bring familiar sleep cues that are permitted by the airline, but avoid adding loose bedding or padding that could create a safety problem.
Parents should decide in advance how they will cope if no bassinet is available: an approved child restraint in a purchased seat, taking turns holding the baby when permitted, or another arrangement consistent with the carrier’s rules. The best plan treats the bassinet as valuable help rather than the single point on which the entire overnight flight depends.
