A Piggio operates out of SFO near hear. I think it is a charter.
IMO. canard, VT, Blown wing, etc. are creatures of Mil flight. On the other hand, if an airframe (commercial) needs tweaking with these things, then it perhaps should not be built, as a new airframe will design benefit the improvement out of its necessity.
IE Vortex generators, belly strakes, even NOTAR.
Maybe not NOTAR, the Tail Rotor is an evil to be wary of.
Managing airstream is a complexity. The last basic improvement that has my endorsement is the Wright's relocation of the Tail to the Tail.
Isn't NASA trying to develop fast jet "Wing Warping"?
There's the Ticket
