The Hainan is in GDS and Hainan timetable. Also bookable on some sites like Skyscanner but not the HU website.
Also some potential new KU flights from the end of the month.
KU117 arrives from KWI 1315 departs to JFK 1525 B77W daily from 26th March T2 allocated but not confirmed yet. Would not be picking up or dropping off pax so will not show on any booking sites and flies direct JFK-KWI on return.
Will only happen if KU are still prevented from flying direct still by the USA but they are hoping for direct flights.
