If you are referring to double pay, its not misinformation, it was negotiated in LOA#20 dated 09 Feb 2010. I have highlighted the change in red for your benefit.

Amend Section 23 L. 8. and 9. as follows:
8. A rerouted regular pilot who is not scheduled to release within four hours of the
scheduled release of the last duty period of his original rotation, or within the
same calendar day of the last duty period of his original rotation, whichever is
later, (the “time limitation”) will receive single pay and credit (or the applicable
pay, no credit for a GS, GSWC, IA or IAWC) for the rotation as flown, plus
single pay no credit for any duty period(s) that extends beyond such time
limitation.
Exception one: If such rerouted pilot is not scheduled to release at his base within
such time limitation due to a circumstance over which the Company does not
have control (e.g., pilot’s origin or destination airport closed, weather on pilot’s
routing, mechanical on pilot’s assigned aircraft) he will receive only single pay
and credit (or the applicable pay, no credit for a GS, GSWC, IA or IAWC) for the
rotation as flown.
Exception two: The time limitation will be 30 hours for an international category
pilot when rerouted into, or while in, trans-oceanic operations.
Exception three: A rerouted pilot who is scheduled to be released at his base
beyond the time limitation will not be entitled to premium pay if he is again
rerouted for the purpose of releasing him at his base within the time limitation.
