does anyone know if theres a limit on how many spg can be transferred to aa in one shot? ie can i do 100k in one transaction?
Quote from SPG.com: With American Airlines, you can transfer up to 79,999 of your Starpoints® into AAdvantage® Miles at a 1-to-1 ratio.
Although you will probably want to do 60k at a time so you maximize the 5k bonus per 20k
