GHB (gamma-hydroxybutyrate) is produced naturally in the human body in very small amounts. When taken as a recreational drug, and especially when taken in combination with alcohol or other drugs, GHB can be extremely dangerous. GHB is a central nervous system depressant.
International flights always allow carry-on luggage, but each airline has its own restrictions as to quantity, size and weight. Some international carry-on policies restrict bag weights to 11 lbs. or less, while domestic flights rarely have a weight limit.
Check your bag before you check in. Each traveler can bring one carry-on bag and one personal item on board, free of charge. We will check any oversized or extra items to your final destination and applicable checked baggage fees will apply. For more information, please see our full carry-on baggage policy.
