Garuda Indonesia is no longer showing as a transfer option for Citi cardholders. Garuda was removed without notice and it’s unclear why it was removed and if it will ever be added back in the future. Garuda wasn’t a common transfer option for most people, although they occasionally had things such as 90% off award flights that made it worth it. No other flexible point currencies offer Garuda as a transfer partner.
