So Spirit shutting down won't affect the FY27 list, but FLL might not be a covered airport anyway based on the increased share of other carriers in CY25. But in any case it's still a covered airport for FY26 so definitely no changes before September 30.
Sort of the case, not exactly though. Once the airport establishes a plan, it shifts to an update categorized as OWT, or only when triggered. In addition, the FY 26 plan is based on FY 24 emplacement data, so in a way, it’s a 2 year data lag. So in this case, it drops below 50% in FY 26, so by that metric, it’ll reflect in the FY 28 plan.
