Mexico City is approximately 9 to 10 hours flying time from London.
By Air
Mexico City is served by Mexico City International Airport .The city has four major bus stations (North, South, Observatorio, TAPO), with bus service to cities across the country, and one train station, used for commercial purposes (intercity passenger trains are now virtually non-existent in Mexico). Though recently, the Tren Suburbano (suburban rail) will be built to serve metropolitan area. There are also several toll expressways which connect it with several other major cities. The city does not have an expressway network that connects points within the city; all cross-city trips must be done on arterial roads. This is one reason why the city's streets are so congested.

By Train
Mexico City is served by the Sistema de Transporte Colectivo Metro, an extensive metro system (207 km), the largest in the western hemisphere, the first portions of which were opened in 1969. One of the busiest in the world, the metro transports more than 4 million people every day, surpassed only by Moscow's (7.5 million), Tokyo's (5.9 million), New York City's (4.8 million) and Seoul's (4.4 million). It is heavily subsidized, and it is the cheapest in the world, each trip currently costing MXN $2 (around EUR 0.13 or USD 0.19). A number of stations display Pre-Columbian artifacts and architecture that was discovered during the metro's construction. However, the Metro reaches only a fraction of the total inhabited area of the city, and therefore an extensive network of bus routes has been implemented. These are mostly managed by private companies which are allowed to operate buses as long as they adhere to certain minimal service quality standards. Electric transport other than the metro also exists, in the form of trolleybuses and the Xochimilco Light Rail line.

The city government also operates a network of large buses, in contrast with the privately operated microbuses, with fares barely exceeding that of the Metro. The city's first bus rapid transit line, the Metrobus, began operation in June 2005 on Avenida Insurgentes. As the microbuses were removed from its route, it was hoped that the Metrobus could reduce pollution and decrease transit time for passengers.
