If your trip is less than 72 clock hours in length then you have only 1 sub window which ends 4 hrs after showtime of the original dropped trip. If this window passes you get paid original trip guarantee. If you are called within this window for a trip and you decline then the hours drop to OTP at 110%. If the original trip is over 72 clock hours then you must satisfy them individually according to the schedule laid out in the contract.
