You will have to make up your OTP in that bid period + the next two. You get paid 125% for OTP. But don't worry, if you don't make you your time in the allotted time, your OTP balance goes into your makeup bank.

You need to call CRS. Right now the assigned code of TRP doesn't help you. You need to get notified that your trip has been revised and that they are offering you a trip as a RAT trip. Or you can decline and get into sub, where you can elect OTP if you wish....
