The Letters of Agreement (LoA) define all controlled airspaces, delegations and coordination procedures between ATS units, both within a FIR and between adjacent FIR. They have to be applied by all members of the French division, and by any member of a foreign division owing a French GCA.
These LoAs contain the definitions of airspaces, the eventual delegations, as well as the coordination procedures to be applied within a FIR.

| LFBB - Bordeaux | v8 : 03/2026 | LOA-FR-LFBB |
| LFEE - Reims | v8 : 03/2026 | LOA-FR-LFEE |

Due to the lack of agreement with Spanish and Swiss divisions, LOAs with these divisions are suspended, thus all traffic shall be systematically coordinated in order to determine transfer conditions. Documents below are presenting airspaces at the interface and a reminder of the coordination procedure.
