In summary, the purpose of this draft Agreement is to publish the great-circle distances to facilitate the calculation of the fee for the use, enjoyment, or exploitation of Mexican airspace, in compliance with Articles 289 and 291 of the Federal Fees Law and Rule 7.31 of the 2025 Miscellaneous Tax Resolution. The update includes the great-circle distances of routes recently established within Mexican airspace, ensuring that individuals and legal entities subject to these fees have access to current technical information. The proposal does not introduce new obligations, costs, procedures, or administrative burdens for private parties, as it does not modify the legal structure of the applicable fees, the calculation method, or the requirements for airspace users. Its sole purpose is to provide updated information to ensure the correct application of existing tax provisions, thereby strengthening legal certainty, consistency, and efficiency in the calculation of flown kilometers.
