Organising a family getaway can be a challenge, as you need to make sure all the essentials are in place and that important documents like passports and boarding passes are in order. Holidays should offer an opportunity to relax, decompress and escape everyday life for a week or two.

Understanding your airline's rules can help things run more smoothly, especially when travelling with children. And there may be requirements you are unaware of. To help make your break run more smoothly and reduce unnecessary worry, we've compiled some key guidance regarding flying with infants and children on Tui, Ryanair and easyJet services, as reported by the Liverpool Echo.

TUI states that infants must be at least 14 days old before they can fly, for health and safety reasons. For those travelling with a baby, all TUI aircraft are equipped with baby changing facilities.

Any pram or pushchair must be foldable, with no restrictions on dimensions or weight if it's being stored in the hold. If you wish to take your pushchair into the cabin, it will be counted as your larger piece of hand baggage and must not exceed 55cmx40cmx20cm and 10kg.

Pushchairs and car seats can be checked into the hold at no extra cost when flying with TUI. According to regulations for all UK-registered aircraft, babies under 6-months-old must be held on an adult's lap and fastened with an infant lap-strap throughout the flight.

Infants aged 6 months to 2 years must remain on an adult's lap, unless you've purchased a separate seat. Should you opt for this, a car seat can be used if required.

You can bring liquid baby food or baby milk, whether shop-bought or prepared at home. You may also carry food for special dietary needs, provided it's necessary for the journey or trip.

Solid baby food is allowed in both hand and hold baggage. There are no limits on carrying powdered formula, you can pack your baby milk powder for mixing during your holiday within your luggage allowance.

Every child, including newborns, must have their own individual passport. The child's passport initially remains valid for five years, with the option to renew for another five-year period.

Upon reaching their 16th birthday, they qualify for a standard 10-year passport.

Like TUI, easyJet states that infants under 14 days old aren't allowed to fly. If your little one is over two years old or celebrates their second birthday during your travels, you'll need to reserve a separate seat for them.

Children aged between two and fifteen cannot fly unless accompanied by someone aged 16 or above. Children aged 15 and under travelling without an adult companion cannot fly and won't be allowed to board.

The carrier considers anyone aged 16 or older to be an adult. From this age onwards, you're permitted to travel with children and those needing special assistance.

Babies with their own seats and youngsters over two years have identical cabin bag and hold baggage entitlements as grown-ups. Should you be flying with a baby on your lap, you're only permitted an extra changing bag for the child.

For each baby or infant, you can take up to two of these items free of charge in the hold, beyond your cabin bag allowance: travel cot, pushchair, double pushchair, buggy, car seat, collapsible or non-collapsible pram, booster seat and baby back carrier.

Baby food, milk and sterilised water are permitted in your cabin bag when travelling with a little one. The standard 100ml liquid restriction at certain airports doesn't extend to baby food, milk or sterilised water, as long as each container holds no more than two litres in total.

Baby changing facilities are available aboard easyJet aircraft. However, you'll need to pack your own nappies and wipes as these aren't supplied on the flight.

Newborns aged up to seven days old aren't permitted to travel on Ryanair services. Babies (aged between 8 days and 23 months) flying with Ryanair must be accompanied by someone aged 18 or above (one baby per adult).

All infants must be seated on an adult's lap and aren't entitled to a separate baggage allowance. Baby changing facilities are available on board at the rear of the aircraft.

Cabin crew are also on hand to warm baby bottles if needed. Should an infant reach two years of age, or a child turn 16 during your journey, you'll need to book 2 single flights instead of a return ticket.

At the airport, you can check in 2 pieces of baby equipment per child (a pushchair plus car seat, booster seat or travel cot) at no extra cost. Ryanair recommends that parents or guardians confirm with their doctor that very young infants are fit to fly.

You're also entitled to bring two items of carry-on baby equipment without charge. This includes a pushchair/buggy, car seat, booster seat or travel cot.

These items must be tagged either at the check-in desk or boarding gate.

When flying with a baby you're permitted to carry sufficient baby food, baby milk and sterilised water for your journey. There's no legal restriction on quantity, though it's worth checking with your airport beforehand.

According to Gov.uk, breast milk can be carried in hand luggage whether you're travelling with a baby or not. Frozen breast milk isn't allowed in hand luggage.

Individual containers of breast milk mustn't exceed 2,000ml. Each container requires screening at the security checkpoint. Airport staff may need to open containers to screen the liquids.
