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.
When flying first class, a number of checked bags can be allowed free of charge. For example, when I flew first class to Madrid for my cousinâs wedding, I was able to check my bag and carry my dress onto the plane, where my things was stored in the first class closet. It helped me avoid worrying and relax.
