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.
However, make sure your carry-on bag is of a size permitted by your airline. Dimensions vary from airline to airline. These two legacy carriers allow each passenger one carry-on bag, and one personal item. In both cases, the carry-on bag must be no larger than 22 inches long, 14 inches wide and 9 inches high. US Airways also stipulates a maximum weight of 40 lbs. Delta says the carry-on bag must fit easily into its carry-on baggage gauges, located close to airport check-in desks. The gauges' dimensions are those of the largest permitted carry-on bag. Personal items allowed in addition to a carry-on bag include a briefcase, purse, laptop bag, camera bag or diaper bag.
