New timelines, same precision required
Mexico’s Agencia Federal de Aviación Civil (AFAC) has published a revised set of operational guidelines for Indefinite Blanket Permit (IBP) processing. The changes, announced in early 2025, affect foreign charter operators with recurring activity across Mexican airspace and introduce stricter documentation standards for fleet updates.
What changed
- Processing windows moved from 30 to 45 business days for complete dossiers.
- Fleet amendments must now be filed at least 14 days before the first scheduled operation.
- Insurance certificates must list each tail individually — blanket fleet policies are no longer accepted without a per-aircraft rider.
What this means for operators
Planning windows are tighter. Operators relying on last-minute aircraft swaps should coordinate with our permits team as early as possible — ideally during the quoting phase — to avoid filing delays that ripple into the trip calendar.
Our recommendation
Start the IBP process 60 days ahead of the first operation of the year, and bundle amendments in monthly batches rather than per-aircraft filings. Our ops team is happy to walk through the new documentation checklist with any operator preparing to file.
