Navan (NASDAQ: NAVN) has upgraded its Singapore Airlines NDC access to a direct connection using the carrier's Amadeus Altéa NDC 21.3 API, according to a company press release. Over 70% of Singapore Airlines bookings on the platform are now made through the NDC channel.

The direct connection, built on Navan's content aggregation platform, gives customers access to NDC-exclusive fares, including eligible corporate and private fares and dynamically priced offers. In markets where Singapore Airlines applies an EDIFACT distribution fee, NDC bookings avoid that fee.

The integration also provides access to fare bundles and ancillary content, including advance seat selection and prepaid excess baggage where supported, as well as faster processing of booking changes, cancellations, and refunds.

"Singapore Airlines is a critical partner in connecting business travelers across Asia Pacific with the rest of the world," said Dane Molter, SVP, Group Travel Marketplace at Navan. "This direct NDC connection will enable us to bring the airline's rich content into Navan and deliver a better experience for travelers that raises the bar for airline retailing."

Gan Cai Fong, General Manager of Distribution at Singapore Airlines, said the airline is "committed to expanding the reach and capabilities of our NDC content for business travelers globally."

The Singapore Airlines upgrade adds to Navan's existing direct NDC connections, which include SAS, Qantas, ITA Airways, and Emirates, as well as a recent Lufthansa Group servicing upgrade to NDC 24.1.
