Flying on an Aer Lingus saver ticket to get to a family wedding in New Jersey. Which means I clear both US immigration and US customs in Dublin.
I know I get a meal on the flight but I'm very snacky and like to take stuff from home to nibble on rather than buy at the airport - obviously nothing with nuts in it.
I know that I have to finish whatever it is before I get off the plane but can I take it on in the first place if I'm clearing Customs in Dublin?
Thanks
