I will be travelling from India to US on Lufthansa and have a stopover in Frankfurt. I'd like to know if I can purchase liquor in India from a duty free shop and if it would be allowed by airport security while in transit through Frankfurt.
Please note that you may not carry liquids bought in duty free shops at airports outside the EU when flying from Frankfurt Airport. This also applies to any duty-free items that you have bought on board a non-EU airline.
Contrary to what is written on their website, the correct answer to this question is Yes, you can. I was able to carry liquor purchased at delhi airport through FRA airport (on 2/18/19). It has to be in a tamper proof sealed bag.
