Narrative:
An air carrier X was in position holding on runway 1L at sfo. We were in position holding for takeoff clearance on runway 1R. Tower cleared air carrier X for takeoff, waited a few seconds and then cleared us for takeoff. Air carrier X was very slow in beginning its takeoff roll. We caught up to abeam air carrier X when tower told us to abort. Air carrier X continued his takeoff and departure. Our airspeed estimated at 80 KTS when abort initiated. Upon clearing the runway, sfo tower stated he was sorry, but policy was 2 aircraft could not take off simultaneously wing tip to wing tip on runways 1L and 1R. He stated he did not realize air carrier X would take so long in initiating his takeoff roll. After reporting all this to my dispatcher, obtaining a new release time for weight and fuel, etc, and allowing the brakes to cool as prescribed in the handbook, we departed west/O further incident.

Title: TKOF ABORT ACCOUNT WING TIP TO WING DEPS NOT AUTHORIZED ON PARALLEL RWYS (NOT AUTHORIZED IF 1 ACFT IS A WDB OR HVY).
Narrative: AN ACR X WAS IN POS HOLDING ON RWY 1L AT SFO. WE WERE IN POS HOLDING FOR TKOF CLRNC ON RWY 1R. TWR CLRED ACR X FOR TKOF, WAITED A FEW SECS AND THEN CLRED US FOR TKOF. ACR X WAS VERY SLOW IN BEGINNING ITS TKOF ROLL. WE CAUGHT UP TO ABEAM ACR X WHEN TWR TOLD US TO ABORT. ACR X CONTINUED HIS TKOF AND DEP. OUR AIRSPD ESTIMATED AT 80 KTS WHEN ABORT INITIATED. UPON CLRING THE RWY, SFO TWR STATED HE WAS SORRY, BUT POLICY WAS 2 ACFT COULD NOT TAKE OFF SIMULTANEOUSLY WING TIP TO WING TIP ON RWYS 1L AND 1R. HE STATED HE DID NOT REALIZE ACR X WOULD TAKE SO LONG IN INITIATING HIS TKOF ROLL. AFTER RPTING ALL THIS TO MY DISPATCHER, OBTAINING A NEW RELEASE TIME FOR WT AND FUEL, ETC, AND ALLOWING THE BRAKES TO COOL AS PRESCRIBED IN THE HANDBOOK, WE DEPARTED W/O FURTHER INCIDENT.
