From the CBA:
1. A pilot in OTP shall be pay protected for the trip guarantee of his original trip for the remainder of the bid period in which the trip began plus two additional bid periods. The trip guarantee for his original trip shall then be deducted from his first paycheck after the pay protection ends (and subsequent paychecks if necessary).
2. If a pilot is assigned an OTP trip, he shall earn trip guarantee.
3. CH for trips assigned in OTP status shall be compensated at 125% of the pilot’s normal pay rate, except that CH earned for trips assigned in OTP status, which exceed the pilot’s OTP eligibility shall be compensated at 100%.
Example:
A 12 CH trip and a 18 CH trip become eligible for substitution. The pilot holding those trips elects OTP and therefore has an OTP eligibility of 30 CH. The pilot flies a 24 CH trip in OTP status. These CH are paid at 125%. With 6 hours of OTP eligibility remaining, (and before that eligibility expires), the pilot flies a 9 CH trip in OTP status. Six of these CH are paid at 125% and the other 3 CH are paid at 100%.
