As with fuel, ACE extends its credit while processing your own direct contracts with the airports and the airport groups which also post their rates (as does ASA) on their websites (ASUR, GAP, CENTRO-NORTE, AICM, etc).

Fees are consolidated by flight in order to assist with billing simplification (which is not how they are processed).

After contracts are awarded, ACE continues to offer its administrative resources to provide you a cost-effective business-relationship with the airport groups .
