And the flight number is KL 810. 777 refers to the Boeing 777 they fly on that route. KLM`s policy is not to interline with 2 separate tickets, but it would be to their advantage not to unload/load your bags on the same plane. As Lenny said, you need to inquire with KLM. And take it in writing. When two airlines have entered into an interline agreement, they usually take care of check-in and baggage for each other`s passengers. This means that travelers only have to check in once for all flights on the itinerary and their luggage is transferred from the first company to the second without having to pick it up and hand it over manually. The downside of an interline agreement is that passengers cannot collect frequent flyer miles for the entire trip. For example, on the Emirates flight, Skywards miles would only be collected on the Dubai-Mexico part of the flight, not on the continuation of the journey. Essentially, it allows passengers to book itineraries with multiple airlines with less effort than booking them individually.
Patrick Roux, SVP Alliances Air France-KLM Group, said: “By working with Sky Express, customers are benefiting from the strength of the Greek national network that begins this summer from our two main platforms. With this new interline agreement, we once again confirm the agility of our network and we want to improve the travel experience of our customers through simplified transfers, additional services and a more advantageous fare offer. KLM only accepts ZED e-tickets on KLM flights. Interline agreements of airlines that currently have no possibility of electronic ticketing have therefore been suspended. . . .
