Clearly we're talking about the civil system and the military operates under different rules, but no US 121 operator has permission from the Administrator.
I'm all ears if you have something better, cos my jet loves a 290-320kt climb....
§91.117 Aircraft speed.
(a) Unless otherwise authorized by the Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots (288 m.p.h.).
(b) Class C and D stuff
(c) Class B stuff
(d) If the minimum safe airspeed for any particular operation is greater than the maximum speed prescribed in this section, the aircraft may be operated at that minimum speed.
No authorization from ATC required, but an advisory "We'll be climbing at 280 knots" is nice. Also, the aircraft can only be operated at it's minimum safe speed. I normally round up about 10 knots. It's not a waiver to push over to barber pole.
There's also no limit in Class E airspace beyond 12 NM. But the Class B at LAX extends beyond 12 miles. Not sure what AngryRat's airline is doing. They could do 270-280 going east bound if that's what their minimum flaps up speed is.
