Under government control by ASA (Aeropuertos y Servicios Auxiliares), which is the sole Jet fuel supplier in Mexico. Although somewhat restrictive in nature, Jet fuel prices for Mexico are posted every tuesday on its web-site (similar in nature to the PLATTS market). ASA does gives volume discounts, but these are not substantial nor specific to each uplift (volume discounts are considered based on yearly consumption), and direct contracts, regardless of volume, will always be the carrier’s smartest, most secure and independent alternative. ACE can provide you access to fuel at all Mexican locations with our own low rates (as well as fuel cards) while processing your own credit directly with ASA, ensuring that you always recieve the best available price.
