Joby is targeting passenger air taxi service launch in mid-to-late 2027. The first FAA-conforming aircraft took flight March 11, 2026. Joby plans to scale production to four aircraft per month in 2027. The company is participating in the White House air taxi program for U.S. operations. FAA type certification is the primary remaining barrier.

Both are eVTOL air taxis targeting FAA type certification. Joby S4 is further along in the FAA certification process, with a conforming aircraft flying since March 2026. Archer Midnight has finalized airworthiness criteria and received a Special Airworthiness Certificate for flight testing. Joby targets commercial service in mid-to-late 2027; Archer targets a similar timeline. Neither has received a type certificate yet.
