Thanks for that. I was concerned it was a year or two like FFCs or ETCs. Though I often prefer to fly UA, I'm a free agent when it comes to leisure travel and can't readily predict when I will use them, esp. as we try to use miles when possible. But 5+ years should be more than sufficient (To put in perspective I still have some AA GCs that were purchased and rebated by my CNB Crystal Card in 2019. Thankfully no expiration, and we finally had occasion to use a couple this year.)
