I personally never had an issue after using it immediately but there have been people who did so its at your own risk.
I did get an email from AMEX titled "Your $200 Airline Fee Credit Benefit". The body of the email confirms that I have selected my airline. I hesitate to wait an entire 24-hour period since I'm losing valuable time.
Surprisingly, I never got an email about the Adobe and wireless credits. I did get an email about my Dell credits.
