If all youve done for the last year is fly between the same two airports with the same 5 captains then even on the first sector it becomes "standard handling and emergencies, runway **, flap **, flexing". Arrival is probably "standard **" Occasionally brief the go-around. How Gash I hear you say but when you can remember every frequency, navaid, and plates for the respective airports is it necessary for the full brief??? Rather be paying attention to ATC, R/T, situational awareness. When both of you know the score this is the preffered method (particularly if its the second time that day for the same arrival and runway). If however you are flying with somebody for the first time then its prudent to give the full brief, especially if they havent been to either airport before.
