A senior (i.e. all) UAL 744 or 777 captain makes about $203 an hour plus a few dollars of international pay if applicable. A whale or 777 FO makes around $139 an hour. Lousy pay for the U.S. but great pay by some expat standards for example.
Under many British style pay schemes (e.g. EK) captain pay longevity is measured from date you upgraded to captain. In almost all U.S. pay systems it is measured from original date of hire so all 744 and 777 UAL captains presumably have at least eleven years of service and would be paid at the highest rate.
