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.
You should check with your airline first, but most domestic airlines permit a carry-on piece of luggage that is 45 linear (total) inches. A common sized bag for carry-on luggage is 22x 14x 9. Most airlines have a carry-on weight limit of 40 pounds. International airlines may have different restrictions for carry-on luggage. Again, it is always best to check with your airline first to get their exact requirements. Airlines enforce all size and weight limits much more strictly now than in the past. Bags are weighed at check-in and many airlines have placed bag sizers at their gates.
