The epiglottis is shaped like a leaf, with the stem attached to the anterior part of the thyroid cartilage. The epiglottis is one of nine cartilaginous structures that make up the larynx (voice box). During breathing, it lies completely within the larynx.piglottitis is mainly caused by Haemophilus influenzae. A person with epiglottitis may have a fever, sore throat, difficulty swallowing, and difficulty breathing. For this reason, in children, acute epiglottitis is considered a medical emergency, because of the risk of obstruction of the pharynx.
Airline Checked Baggage Regulations. 1  Baggage check or airport check-in is a service offered by commercial airlines, allowing flyers to have their luggage carried in the cargo area of an airplane. Before passengers board their plane, they turn over their luggage to the airline; they are then united with their items at the destination.
The general allowance per passenger depends on the policies of the particular airline. On U.S. domestic flights, it was typical for an airline to allow passengers to check up to 2 pieces of lugagge that are up to 50 pounds (22.7 kg) each free of charge (total 100 pounds = 45.4 kg), and this can be exceeded for a fee.ertain airlines operating under the Piece Concept may add additional checked baggage allowance for their Elite Level fliers (see below sections). Weight restrictions are per bag, unlike the Weight Concept (described below).
