Inflight Event / Encounter Wake Vortex Encounter; Inflight Event / Encounter Loss Of Aircraft Control
Flight Crew Regained Aircraft Control
Environment - Non Weather Related; Procedure
Immediately after a B737 was cleared for takeoff from 19L; we were cleared to line up and wait and to keep the B737 in sight. Just as the B737 lifted off the runway; we were cleared for takeoff. By the time we began our takeoff roll; the B737 was about 2.5 miles from our location. We rotated past where the B737 had rotated and our climb profile was beneath theirs. At about 300 to 500 feet AGL we encountered wake turbulence which rolled the aircraft both left and right about 15 to 20 degrees. I advised the tower of our encounter as he handed us off to departure control.
B737 Captain reported encountering wake turbulence in trail of a B737 on takeoff from LAS.
