Here's what I found online in terms of the 2015 Commission decision and the commitments:
https://ec.europa.eu/competition/mer...4564413_EN.pdf
For (2) and (3), I see EI made commitments to provide access to other carriers (via Special Prorate Agreements for interline ticketing, access to Frequent Flyer Programmes, etc.) and there is a provision that if EI increases capacity on a route to a hub, any SPA will be valid on that extra capacity too, but I confess I don't see anything about KLM guaranteeing a minimum number of passengers. Maybe I'm looking in the wrong document - could you point us to the right one? Thanks!
