Lucky Air cancelled its Kunming–Udon Thani charter flights for September 2026 (first slated for 8 September) after its charter partner broke the contract. Tour firm Max Tour Education is refunding paid tour fees in full without waiting for the airline. If you sell or hold bookings on this route, contact affected customers now and check whether your own refunds or rebooking commitments are covered. Confirm the airline's written cancellation notice, expected Monday, before deciding on alternative routes or dates.
