It does absolutely nothing if pilots continue to allow "rolling rest" to occur. There are at least 5 other LOIs addressing this same topic. All this one does is present an avenue for pilots to report their companies to the Feds, basically putting the ball in the pilot's court so to speak.

Legally speaking, how companies actually report and record rest makes it look perfectly valid in most cases. If you were to report to duty at 09:00, how does your company record when your rest started? 23:00 the previous night? Looks fine to me.

It is also up to you to determine if you've gotten the legal rest requirement, meaning if you weren't informed that you are on rest at 23:00 for an 09:00 show, you didn't get 10 hours of legal rest.

Ball is in our court. What are we going to do?
