Domestically, air travel between Paris and some of France's largest cities such as Lyon, Marseille, or Strasbourg has been in a large measure replaced by high-speed rail due to the opening of several high-speed TGV rail lines from the 1980s. For example, after the LGV Méditerranée opened in 2001, air traffic between Paris and Marseille declined from 2,976,793 passengers in 2000 to 1,502,196 passengers in 2014. After the LGV Est opened in 2007, air traffic between Paris and Strasbourg declined from 1,006,327 passengers in 2006 to 157,207 passengers in 2014.
