Comfort is the key but still make sure you look good as you will have more of a chance to be upgraded.
Drink plenty of water and get up & walk around every hour to prevent blood clots.
Get plenty of sleep and set your watch to the local time of your destination.

Comfortable clothes for the flight and extra jumper/jackets for disembarkation if your destination is a cold climate.

Also, plenty of fluids and movement breaks for everyone!

Loose fitting cotton clothing that can breathe and shoes that can slip on and off easily.

An IPad with their fave shows is helpful to keep them amused.

A shawl is great,you can use it many ways.

No jeans, belts or boots. Wear something that is loose around the waist like a dress or pants and a top. A Cardigan is easier to slip on and off. Always bring a pair of sock. Wear layers as it can get cold on the flight. Your 16 month old can wear her pyjamas if they are easy to do up and undo – whatever is most practical. Don’t forget a change of clothes for her and a toothbrush for you.

All the best advice has already been given here, loose or comfortable clothing is the key as could not think of being stuck in restrictive clothing or shoes for a large period of time.

I would choose comfortable, loose clothes for you and similar for your little girl. Remember, you’ll want easy access for nappy changes. A friend gave me a great tip for travelling with babies and toddlers – pack spare clothes (more than you think you’ll need) in large ziplock bags. Sometimes accidents can happen and if something gets spilled into your nappy/ travel bag, the spare clothes are gone.

Firstly comfort clothes for Mum, but to make bub super comfy a loose onesie plus their favourite blanket for snuggles + their night time huggies.

Loose fitting clothes, lots of books and drawing games sticker books and toothbrush for you lol

Leggings and a long comfy too, layer so you can undress if you get hot, same for bub

Wear whatever is most comfortable. The plane will be air conditioned, so no need to have heaps of layers on

For yourself something loose and comfy. For your child i would pack a spare outfit or two incase she gets sick or messed up while eating. Ones that are supper easy to change her nappy in. as the toliets on the plans are cramped and annoying to change nappies. . I would also check with the airline what kind of food they will supply your child while flying. Some provide bottled baby/toddler food other might not. You might need to pre book a special childs meal before leaving. And if your child still has the occasional bottle i would check on the rules in regards to that before leaving( supply of water or heating for it).

Go for comfort and layers. Some planes are too hot some too cold and some just right. I put on long sleeve t shirt and tracy pants with jumper and t shirt in bag if too hot so I can change. Also a jumper with a zip so you can have it done up if too cold or undone if warmer.

the whole family should Dress for comfort, it makes it easier to relax

One mistake I made on my first overseas trip was not advising my bank in advance. They then froze my accounts whilst away!! As for clothing – go for comfort, a nice pair of track pants/tights or leggings. I agree with layering. Have a great time.

Wear clothes that are loose and comfortable as on a long trip you will twist and turn in your seat. Comfortable shoes etc, Add a light jumper that can be taken on or off to suit . Find out what the weather will be like when you land so you are prepared. Same for your daughter, plus a couple of changes for her onboard. Happy Holidays/

Make sure you dress comfortably! Nothing more important than comfort on long trips. Same for your little girl, comfortable and easy to change in case of accidents. Also, layers are handy, strip off when hot and pile it all back on again for cold.

Dress for comfort and ease to get on and off! Also take a change of clothing for yourself as nappies have a habit of leaking on flights – something to do withe the air pressure. I also take more nappies than you think you could need for the same reason. Take a favourite blanket as sometimes it can get cool and the airline blankets aren’t the softest.
