On the other hand, about the On-board Wi-Fi we share with you that, to date, we continue to implement the Wi-Fi service throughout our fleet so, for now, this is available only on some aircrafts, however, we hope this become a reality very soon in all our routes and planes.
Finally, regarding the lack of USB ports, we share with you that this was due to the configuration of the aircraft that operated your flight as it has an USB port for every three seats in the economic cabin; regarding this point it is important to mention that this varies from one aircraft to another according to the route they operate.
