1 Raw shrimp should be firm, translucent, and somewhat shiny, with no noticeable odor. Most of the time, raw shrimp will have the legs and shell, and often the head attached.  Frozen shrimp, cooked or raw, should be defrosted in the refrigerator overnight, before attempting to clean or devein them.
Most airlines in the United States, including American, Delta and United, allow carry-on bags that are no more than 22 inches long, 14 inches wide and nine inches high.
Carry-on baggage size regulations are set by each airline, rather than the Transportation Security Administration or another governing body. Southwest Airlines requires that carry-on baggage measures no more than 10-by-16-by-24 inches. When you arrive at the Southwest counter in the airport, you'll see a receptacle in which your carry-on bag must fit comfortably to be permitted onto the airplane.
