European business travel management platform TravelPerk has added content via Lufthansa Group Airlines' New Distribution Capability application programming interface. The connection will enable TravelPerk users to access Lufthansa's NDC Smart Offer fares, which are its cheapest available fares, and to access the "widest range of ancillary options," according to TravelPerk. Over the past few months, TravelPerk has run a beta test of the connection with a small group of its clients and reports that some have had savings as high as 37 percent on the cost of their flights within Europe.
