The FAA will host a Domestic Datalink Services (DDLS) Industry Day on December 8–10, 2026, from 9:00 AM to 5:00 PM ET at FAA Headquarters, 99 New York Ave NE, Washington, DC 20226. The event is market research only and voluntary; no contract award will result, and attendance, travel, and capability-statement preparation costs are at the vendor’s expense. It seeks commercial marketplace participation from vendors with DDLS-relevant competencies under NAICS 517810 to share developments supporting FAA requirements development, lessons-learned application, and acquisition strategy. The FAA may hold one-on-one discussions and may use information obtained to support a potential future SIR, but this is not a solicitation or RFP and creates no government commitment. Submitted materials will not be returned, and vendors should mark proprietary data accordingly.
