We are flying dirctly into Key West from Atlanta on a CRJ-700 jet. My brotherinlaw is scaring the heck out of my sister by telling her there are serious luggage restrictions and she has to pack extra light. Is this true? I have to say that he will probably be the one with the heavy suitcase, because he tends to wait til the last minute to pack and then overpacks. Any info would be appreciated, everyone here has been a tremendous help, Thanks.
