British Airways Adds Viva as a Codeshare Partner in Mexico

British Airways has added Viva, the Mexican low-cost airline, as a codeshare partner. For travel from March 28, 2027, BA's flight code will sit on Viva-operated flights to 13 Mexican destinations, and you can book them on ba.com today.

The network is built around two hubs. Connections run through Mexico City and Cancun, with Viva carrying you onward to places like Guadalajara, Monterrey, Oaxaca, Mérida, Los Cabos, Puerto Vallarta and Tijuana. If your trip ends somewhere other than the gateway city, a BA booking can now carry you the rest of the way.

• Where to book: ba.com, for travel from March 28, 2027.
• Hubs: Mexico City and Cancun, each with its own list of Viva destinations.
• Earning: members of The British Airways Club will be able to earn Avios and tier points when traveling on these flights.

This fits travelers connecting through Mexico City or Cancun with BA who want to keep going inside Mexico. If you are flying to Mexico for a beach or a big city, it does nothing for you.
