I think using premade formula is the easiest way to go; its what we use for traveling now (and what we will use on a plane). You just open it and pour into the bottle and you’re good to go. The same discarding time frames/rules apply as to powdered formula.

I would take a couple of bottles and probably just rinse them in really hot water at the airport between feedings (I’d probably put a little soap in them, shake them up to get the soap all over the inside, and then rinse well in hot water).

The premade liquid will be heavier in your carry-on than powder, but I like them because they are so easy to use. If you do go the powder route, I would definitely either get the single-serve powders or pre-package the powder yourself into single serve baggies.

Hmmm, I think I would take 2 extra. Once you open a container, if you are not going to use it all within 2 hours, maybe you could ask the stewardess if they would mind popping the leftover into the airplane fridge so that you can feed it to LO later on in the flight.

Does your LO calm with a bottle, even if she isn't really hungry? If so, maybe bring a 3rd in case she needs to sort of “comfort nurse” during the flight?

How do the flight times match up with her established feeding schedule (if she has one)?

“They” say its helpful to babies to suck on a bottle/nipple during takeoff/landing, so you’ll want a little extra for that purpose.

I would probably bring 2 extra premade liquids and then 1-2 single-serving powders for emergencies; but I tend to overestimate how much LO will eat!

I think that according the security rules in the US--it will be easier to get premade formula through otherwise you have to buy expensive water on the inside of security.
That may only be for the return trip--not sure about security/FAA in Heathrow.

Good luck!
