As previous poster stated. Very hard to say.
B757 and B767 in our company, and I suspect other Boeing types.
Above FL 200 Minimum Airspeed is Vref 30 + 80 knots or 'top of the amber display' on the ADI speed tape, which ever is greater on aircraft so equiped
or those aircraft not having a speed tape, Vref 30+100 knots.
Vref 30 is the reference speed for Flaps 30 (max flap) and as such varies greatly with weight.
If you wish further info I would suggest approaching a few of the airlines.
