Seems they will charge a subscription to access this - at first thought I wondered if this is the best option, and not just charge a per-leg fee like https://flightfox.com https://flightfox.com (who do concierge travel services and I love them) but I suppose, if you get the flight schedule you want, many people will instead jump and book direct with the airline. This can be good, if the flight aggregator is a behemoth and will not help you in case of problems, or bad if the airline is a behemoth.
