If you travel by bus in Mexico you will have one of the most pleasant surprises as Mexico has an excellent intercity bus system with many classes of service available to fit your needs.  Mexico has one of the most modern bus fleets in the world and the luxury classes are even better than most airplanes.

Depending on the city, the bus terminal may be close to the city centre or for the newer terminals they might be outside the downtown area, but don’t worry as all major bus terminals have official “taxi counters” inside the terminal where you can hire one to safely take your destination. Also if you have access to Wi-Fi or you have data on your phone you can even call an Uber to pick you up in some cities.

The different bus classes in Mexico

Second Class (Segunda Clase): The most basic is usually Second Class, which can be comfortable, without a/c and making stops at many points along the way (few have a/c). Although very affordable if you can upgrade it is highly recommended.

First Class (Primera Clase) :These buses are very nice, with reserved seats plus more leg room, with a/c, restroom, and movies. A sandwich and a drink is usually provided. They make few or no stops along the route. Between major cities there is often a bus every 15/30 minutes, and there is no need to book in advance except during busy holiday periods. However, many companies have online booking facilities.

Luxury Buses (De Lujo or Ejecutivo): The top of the line are a few companies such as ADO-GL, Ave Senda, ChihuahuensesETN, Futura, Tufesa HCTuristar Ejecutivo, and UNO, who operate luxury buses with 2+1 seats across which almost lie flat, similar to business class airline seats. These buses run mainly on the busiest routes. They provide a snack with sandwich and cookie, and a permanent drink station in the back of the bus with hot water for tea and coffee. The buses make few or no stops along the route and on longer journeys they often travel overnight. Tickets can usually be purchased through their websites.
