What this means for fares and GDS/PNR pricing

For B2B sellers (agents, consolidators, TMCs, airline distribution teams):

The PSC is ticketed as part of the fare/airport taxes at issuance — so published fares, YQ/YR components and tax splits in GDS/booking systems will reflect the new rate once airlines and BSP/ARC processes are updated. Expect ticketing engines and BSP reconciliation to require a small release & retesting window.)
Airlines may absorb, partially absorb, or pass through the full increase depending on route competition, yield management and corporate contracts. On highly competitive short-haul sectors carriers could delay fare moves; on long-haul or peak leisure sectors the PSC rise will more likely show as higher total ticket prices. (Industry reaction will be airline- and market-specific.)
For consolidators and wholesalers: update your markup models and fare reprice rules. A fixed per-passenger increase (฿390 ≈ US$12–15) matters more for group bookings and low-fare bundles than premium itineraries.
