Madelinesmum, yep you can take formula. I'd opt for the single serve sachets just to make it easy for yourself and they can't be confiscated for being open! DS2 is breastfed but I am taking UHT milk for him in little cartons.
Someone else might have more of an idea how Marti but you can turn roaming off on your phone. Maybe just to be safe have your carrier block it?
Its getting oh so close for so many of us! I'm not quite sure what I should be doing either now. Hawaiian have amended our Vegas/Honolulu flight times, we don't depart any earlier but we arrive 20 mins earlier
must be expecting a big tail wind
work in our favour really, just means we can be in the next comfy bed a bit sooner as its an evening flight and late nights aren't fun with kids!
