16 Hour flight - 1 year old - formula?

[desertboot]

Hi, sorry if this should be in travel - we have a 16 hour flight coming up with our one year old, then a connecting 3 hour flight.
She is formula fed at the moment, about 4 bottles a day. I still do the whole boil water, wait half an hour to mix, sterilise bottles etc. Should I take just 5 bottles and 5 cartons of premade formula, do the staff give you boiled water?
Sorry to be clueless, have always breastfed before, so don't know the whole bottle rigmarole.
We are fortunate enough to be bringing down the neighbourhood in business class, don't know if that makes a difference. Can just bottled non boiled water be used if we take formula powder?
Also we are leaving from an airport where security is lax to say the least, so there is no problems with taking liquids, powder whatever......
Also, when should babies not be using teats anymore?
Thanks for any tips or help!

You can buy formula cartons airside (always buy extra as flights seem to make kids thirsty) or staff will get you water or milk (usually pretty quickly but do factor in may be a wait if you have impatient child). Have travelled a lot with ff dd and tbh carton better as you have control over when to feed.

Dont forget that need supplies or know where to get them when Get to destination (identifying what and where to get formula often quite an operation).

Oh and strictly advice here is no bottled water (although bizarrely not in other countries which is odd).

I'd take cartons, much easier.

If you use bottled water it should be low-sodium water suitable for babies (they usually have a picture of a baby on the bottle). To be safe you still need to boil it though so that the water is hot (above 70 degrees) when you mix the powder so the powder is sterilised.

Generally advice is to move from bottles to cups at 12 months, as bottles are bad for their teeth - and clean teeth after milk. From 12 months they can have full fat cow's milk instead of formula.

Thanks! I think I will just go cartons, much easier, and have started on sippy cups today.
She has cow's milk as well, but it is hard to get fresh where we are, so it is not often.
Thanks for replies.
