Important Caveats
ExpertFlyer does not book tickets. Once you find availability, you complete the redemption on the KLM website or by calling reservations.
- Connections: search each segment individually as a direct flight for accurate award and upgrade availability. Do not search origin to destination for connecting itineraries.
- Codeshares: award and upgrade inventory is not valid for codeshared flights. Always look up the flight under the operating carrier.
- Some airlines do not publish award or upgrade inventory to the GDS and cannot be searched.
