I have looked up loads of threads on this but I can't seem to find the answer I need....
I know you can reserve cartons of formula and baby food to collect at Heathrow after security, which is fine and which I've done.
How on earth does it work on the return journey - I cant imagine we're going to find anywhere to buy Aptimil after security at JFK. And I expect U.S. security to be less inclined to wave a collection of cartons through. I presume we'll have to take powder (as I guess it'll be easier to taste that if carried in a travel dispenser), but I'm not very sure we'll be able to persuade BA staff to give us freshly boiled hot water...as I'm presuming the water they use isn't freshly boiled all the time...
Any other advice you could give us would be brilliant. He's just started properly crawling now, and our flight is in 2 weeks...not perfect timing.
