My husband and I take empty refillable bottles through security. There is normally a point to refill them the other sideYeah mine is pretty much just tea or beer!
I feel like crap if I have anything less than about 2.5 litres, but prefer to have 3-4. I think my body is just used to it. I especially don’t know how people go without water on long haul flights, it dehydrates you so much. I practically have to remortgage my house to buy the big bottles of water in the airport the amount I take
So they we only need to buy 1 big bottle each
