I am wondering if the recently enacted FAA Reauthorization Act will affect the expiration of these types of credits? This is an except from the Senate's press release:

• Sets Minimum Standards for Airline Credits: When airlines offer credits or in lieu of a refund, credits must be good for at least 5 years—so they don’t expire before they can be used.
