Viva Aerobus vs Volaris carry-on
Viva Aerobus and Volaris are Mexico's two ULCC slugfest carriers, both selling sub-100 USD fares on US-Mexico routes. Viva's carry-on sits at 22 x 16 x 10 in and 22 lb on its base fare versus Volaris at 57x40x25 cm and 10 kg, so sizes are nearly identical. Volaris's base fare historically included a cabin bag, while Viva's Switch fare includes only a personal item, making Viva more punishing for unprepared travelers. Viva hubs MTY with heavy US expansion, while Volaris centers on MEX, GDL and TIJ with deeper US Pacific coverage. For MTY-bound travelers from Texas, Viva is usually cheaper. For Los Angeles or the Bay Area, Volaris generally has more frequencies.
