The flight test program included a much-publicized return flight across the United States and in another stunt, a successful attempt at a load-carrying record was set by lifting a 4,600 lb (2,090 kg) "payload" of "33 girls, two pilots, and a mechanic" to 10,200 ft (3,110 m) in 25 minutes.

This featured 18 seats, a lavatory, and a separate baggage compartment.

The first of these machines (NC98N) was purchased by [Vous devez être inscrit et connecté pour voir ce lien] for use as an engine testbed, but also as an executive transport.
In keeping with this latter role, a deluxe interior was fitted in place of the passenger compartment, which included an office and sleeping berths.
The second aircraft (NC10N) was selected for evaluation by [Vous devez être inscrit et connecté pour voir ce lien] for use on a cross-United States route.

Lindbergh himself flew the Patrician to various stops across the United States to research routes and provide an opportunity for TAT to generate publicity for the planned service.
One of these stops turned into a fiasco when the Patrician became bogged in mud while landing at [Vous devez être inscrit et connecté pour voir ce lien], [Vous devez être inscrit et connecté pour voir ce lien], requiring the various dignitaries aboard to be unloaded while the aircraft was dug out.
