ADO is the bus company you will use most in southern and eastern Mexico. They run first-class and luxury coaches between Mexico City, Oaxaca, Veracruz, Villahermosa, Palenque, Merida, Cancun and everywhere in between. If you are heading south of Mexico City, ADO is probably your ride.

The full name is Autobuses de Oriente, but nobody calls them that. Just say ADO (ah-deh-oh) at the terminal and people know what you mean.
ADO Service Tiers
ADO runs three levels of service. Regular ADO is the standard first-class option — comfortable seats, air conditioning, a bathroom, sometimes a movie. ADO GL is the step up with wider seats, more legroom and electrical outlets. ADO Platino is the top tier with lie-flat seats on overnight routes, though it only runs on major corridors.
The price difference between regular and GL is usually 100-200 pesos. For anything over four hours, GL is worth it.
ADO Subsidiaries: OCC, AU, Sur
ADO owns several other lines that share their terminals and booking system. OCC (Omnibus Cristobal Colon) runs routes through Chiapas and the Pacific coast — the Oaxaca to Huatulco corridor, Tuxtla Gutierrez, San Cristobal de las Casas. AU covers central routes through Puebla and Tlaxcala. Sur handles some Guerrero state routes.
You can book any of these through the ADO website or at ADO terminals. They all show up in the same booking system.
Key ADO Routes From Oaxaca
Oaxaca is an ADO hub. From the first-class terminal on Calzada Niños Heroes de Chapultepec you can catch direct buses to Mexico City (6 hours, leaves every couple of hours), Puebla (4.5 hours), Villahermosa (10 hours overnight), and Veracruz (7 hours). OCC runs the coastal routes from the same terminal down to Puerto Escondido and Huatulco — though those mountain roads make the 6-hour ride feel longer than it is.
The Oaxaca terminal has a decent waiting area with food stalls, bathrooms and a luggage storage counter. Get there 30 minutes before departure for assigned seating.
Booking ADO Tickets
ADO has the most functional online booking system of any Mexican bus company at ado.com.mx. You can pay with international credit cards and get an e-ticket on your phone. This is useful for holiday travel when buses sell out, but for regular days you can just show up at the terminal and buy at the counter.
One thing to know: the website sometimes shows different prices than the counter. Usually the online price is slightly lower, but not always. If you are flexible on departure time, ask the counter agent for the cheapest option — they can see all departures.
