The first flight with a baby produces more parental anxiety than most other firsts in early parenthood. It is the combination of a public space, no escape, a screaming baby, and other passengers who may or may not be sympathetic. The reality is usually less bad than the anticipation, particularly with some practical preparation and realistic expectations.
Flying with a baby under about six months is in some ways easier than flying with an active toddler. A young infant sleeps through much of a short flight. A walking, opinionated two-year-old who cannot sit still presents a different set of challenges.

Age and Medical Clearance
Most major airlines accept infants from two weeks of age. Some set their minimum at seven days, others require four weeks. Check the specific airline's policy before booking.
Very young babies, particularly those born prematurely, may need a letter from their GP or paediatrician confirming they are fit to fly. Premature infants may have difficulties with the reduced oxygen levels in a pressurised cabin and these cases need individual medical assessment. The standard threshold is often 37 weeks corrected gestational age, but this varies and should be confirmed with the medical team.
For healthy term babies from around two to four weeks, there is no standard medical requirement for a letter, though some airlines ask for one. Calling the airline to confirm before the flight avoids problems at check-in.
Lap Infants and Seat Purchase
Children under two travel as lap infants on most airlines, usually free on domestic flights and at around 10 per cent of the adult fare on international routes. A lap infant has no guaranteed seat, no seatbelt, and no restraint in the event of turbulence. The parent holds the child for take-off and landing with their own seatbelt fastened across them both, which aviation safety researchers have noted is not ideal.
Purchasing a separate seat for a baby and using an approved car seat is the safest option and is permitted on many airlines. The car seat needs to be forward-facing or rearward-facing within the airline's approved dimensions, and it must carry a specific aviation safety approval mark. Check with the airline before assuming any given car seat is permitted.
For short flights, many families take the pragmatic approach of lap infant travel and accept the comfort trade-off. For long-haul, a separate seat becomes much more worthwhile.
Some long-haul aircraft have bassinet positions at bulkhead rows, available by request. These accommodate smaller babies (the weight and length limits vary by airline and aircraft type) and are well worth requesting if applicable. They are usually allocated closer to the flight date and are not guaranteed.
Ear Discomfort
The cabin pressure in an aircraft is regulated but not to sea-level pressure: it typically corresponds to an altitude of around 1,800 to 2,400 metres. During ascent and descent, pressure changes in the cabin can create a pressure difference between the ear canal and the middle ear, which causes pain or discomfort until the Eustachian tube equalises it.
Babies cannot voluntarily equalise by yawning or swallowing on cue. Sucking and swallowing help: feeding (breast or bottle), or offering a dummy during descent is the standard recommendation and works well in most cases. The period of discomfort is typically minutes, not the whole flight.
Older toddlers and children can be given a sweet to suck, asked to yawn, or offered a drink. Chewing gum works for older children.
A baby or toddler who has active ear infection or significant congestion from a cold may find pressure changes considerably more painful. Flying with an ear infection is uncomfortable for anyone; in a baby who cannot explain what is happening, it can produce distress that is hard to manage. If possible, postpone flying during significant illness. If not possible, nasal saline drops to reduce congestion and paracetamol given before the flight may help.
Managing the Flight
Pack more of everything in hand luggage than you think you need. Nappies, spare clothes (at least two complete outfits), snacks, and comfort items. Nappy blowouts at altitude happen in sealed metal tubes with limited changing facilities.
Infants who are in a good feeding and sleep pattern often feed and sleep through short flights. Timing the flight around a sleep window helps.
Toddlers need entertainment. Books, small toys, sticker books, and age-appropriate apps loaded offline are all options. Screens on flights are generally accepted by most parents who would otherwise be more restrictive at home: a long flight is not the time for a principled stand on screen time.
Expect some noise. Babies cry. Toddlers have meltdowns. Other passengers have all been a child on a flight. A matter-of-fact attitude, offering snacks and activities before problems escalate, and not catastrophising inevitable brief crying produces a calmer atmosphere for everyone.
Bulkhead rows and seats near the middle of the aircraft tend to have more floor space. Booking these where available gives more room for a toddler to be put on the floor briefly if needed.
After the Flight
Jet lag in young children is real and can take a week or more to resolve when crossing several time zones. Getting onto the destination time zone as quickly as possible, with exposure to daylight at appropriate local times, is the main approach. Expecting disrupted sleep for the first few nights prevents disappointment.
Dehydration on aircraft is worth managing proactively. The cabin air is dry. Feeding frequently and offering drinks helps.
Key Takeaways
Most airlines accept infants from two weeks of age, though some require four weeks and a letter from a GP for very young babies. Ear discomfort during ascent and descent is caused by pressure changes and can be reduced in infants by feeding or offering a dummy; in toddlers by swallowing, chewing, or yawning. Babies under two fly for free as lap infants on most airlines but have no guaranteed seat, which limits safety equipment options. Car seats that meet aviation safety standards can be used on many airlines if a seat is purchased. Expecting difficulty but preparing practically produces a much better experience than assuming everything will be fine.
