About Volaris
Volaris is a Mexican ultra-low-cost airline. It is headquartered in Mexico City and spreads its flying across several bases, with Guadalajara, Tijuana and Mexico City the most important. The domestic network is wide and point to point, often linking secondary cities directly without a stop in the capital. Across the border it serves many US cities with large Mexican communities, and affiliates in Costa Rica and El Salvador extend the brand into Central America and parts of South America. There is one economy cabin, no alliance membership, and a fare structure where bags and seats are added to a basic ticket.
When you search a Mexican domestic or US to Mexico route on IATA.co, Volaris fares appear in your search results whenever our flight suppliers offer them for your route and dates. Low-cost carriers are not distributed everywhere, so results can vary from one search to the next. Searching is live in the booking portal and the flights API, and you pay from a prepaid balance. Check the fare rules shown with each option for what the ticket includes.

Volaris is a low-cost carrier, based in Mexico, operating mainly from Mexico City (MEX). It is not part of a global airline alliance.
Booking Volaris fares as a travel agent
Travel agents book Volaris fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live Y4 fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. Volaris results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
