Transporting liquids, including alcoholic beverages purchased at duty-free shops, through airport security checkpoints onto connecting flights involves navigating specific regulations. These regulations often require the liquids to be sealed in a Security Tamper-Evident Bag (STEB) provided at the point of purchase, accompanied by the purchase receipt. This process allows passengers to carry liquids that would otherwise exceed standard carry-on restrictions.
The ability to carry duty-free purchases onto connecting flights offers convenience for travelers wishing to bring home souvenirs or gifts. It simplifies the travel experience by removing the need to repack or check these items separately. Historically, stricter regulations regarding liquids in carry-on luggage were implemented in response to security concerns. The STEB procedure was developed to allow passengers to continue enjoying duty-free shopping while maintaining necessary safety protocols.
