Volaris has a complex check in system that relies on phone apps and computer know-how. Many of their clientele cannot keep up with this technology. Simplify your check in procedures and get off the internet grid. The food selection is horrible and overpriced. The coffee is instant Nescafe which is an insult to the great coffees of Mexico. Also, it costs 30 pesos per horrible cup. , there is nothing free, no drink, no cracker, no nut. Definitely bring your own food and drink, or your taste for junk food and an open credit line.
