Hi lovelies so we’re fraying back from Sharm to the uk Luton airport on Sunday eve and we want to buy some tobacco and spirits on the flight. Now online it says 250g per person and up to 4 litres of spirits. Obviously have to be over 18 to buy but it says 17 to declare. My son is 17. If I purchased 250g of back for both me and my partner each and 4 litres each am I able to buy myself more tobacco and give it to my son to put in his carry on or no?
