After the -100 were made, Boeing started making -200. The -200 has a longer range, but still carries the same number of people. This is because airlines said the -100 could not fly long distances. The -200 is made in passenger type (-200B), freighter type (-200F), Combi type (A plane that carries both cargo and people; -200M) and convertible type (a plane that can be easily changed to carry cargo; -200C).
