In 2026, the Chase Ultimate Rewards program maintains a powerful list of 11 airline transfer partners, allowing cardholders to transfer points at a 1:1 ratio. The primary U.S.-based partners are United Airlines, Southwest Airlines, and JetBlue. International partners include British Airways, Aer Lingus, and Iberia (all utilizing the Avios currency), as well as Air France-KLM (Flying Blue), Singapore Airlines, Emirates, Air Canada (Aeroplan), and Virgin Atlantic. This diversity allows travelers to "unlock" flights across all three major global alliances: Star Alliance (via United/Singapore/Air Canada), SkyTeam (via Air France-KLM/Virgin), and Oneworld (via British Airways/Iberia). A high-value "pro-tip" for 2026 is that transferring points to Virgin Atlantic often provides the best value for booking Delta-operated flights, while Air Canada Aeroplan is widely regarded as having the best "sweet spots" for business class redemptions on diverse international carriers like Etihad or Oman Air.
