Company Policy; Human Factors
Tower cleared us to line up and wait Runway 26L. After the Captain lined us up; we were in position approximately 45 seconds and Tower directed us to exit the runway at Taxiway E13. We were placed behind another Company aircraft and another aircraft. After we exited; a Gulfstream if I recall correctly was cleared on and departed; followed shortly by another aircraft. The approximate additional fuel burn for us was 300 pounds. This was fuel we were not planned for and did not need to burn. By the time the Gulfstream departed we could have been three miles down range; this was an unacceptable and ridiculous delay. We have no control over Tower prerogatives; but I have never heard of an aircraft directed to exit the runway so another non priority/non emergency aircraft could depart.
B737 First Officer reported being told to exit the runway they were previously cleared to; to be re-sequenced for departure behind another aircraft; causing delay.
