Please contact the WASA Team under cads@icao.int. should you have any questions or comments regarding the WASA.

Kindly ensure that your State focal points file their Air Services Agreements and traffic data. To receive further information or to address any discrepancies found in ICAO’s WASA database or maps, please contact the WASA Team according user email.

• The WASA Database includes agreements that are officially registered with ICAO (Art. 83 of the Chicago Convention), as well as other agreements and arrangements, which are publicly available.
• States have an obligation, established under the Chicago Convention, to register aeronautical arrangements, including air services agreements, with ICAO. ICAO has promulgated rules to govern the registration process which can be found in Doc 6685- Rules for Registration with ICAO of Aeronautical Agreements and Arrangements. Including agreements in the WASA does NOT replace the official filing obligation through the aforementioned process.
