CEOFLIGHTS Personal Travel Managers work with a network of unpublished, negotiated fares that are not available on platforms like Google Flights or Expedia, routinely delivering savings of up to 60% against standard published business class pricing on international routes.

The best months to book this route for maximum value are January, February, March, October, and November.
