Can tourists go higher than 22km? If so, what's the highest they can go?

The MiG-29 Flight is the only fighter aircraft available for Supersonic Flights and Edge of Space Flights. The MiG-29 Fulcrum is also a modern fighter aircraft, belonging to the 4th generation. Given the fact that even European Air Forces still use the much older MiG-21 Fishbed, it is very surprising that tourists can fly in such modern aircraft to an altitude of up to 22km. 17km is guaranteed, the altitude reached depends on the weather and the air temperature. The MiG-29 Fulcrum is a Mach 2+ interceptor and a state of the art multirole fighter jet.

I'm excluding one-shot, special (and outstandingly pricy) deals such as the tourist who went to the ISS. Also, sub-orbital spaceflights for space tourists with Virgin Galactic or others aren't available yet. Same for more ambitious programs such as DearMoon.
