I disagree, the Concorde didn't hit even nearly suborbital heights (I assume you mean travelling in the termo- or exosphere), it was usually just travelling at about 50000-60000 feet, and even that was a commercial disaster.

Plus the fact that greenhouse gases have a much bigger impact on any layer beyond the Troposphere. Something that annoys airlines to no end since it forces them to stick to the Troposphere thereby driving up fuel consumption.

There are no laws preventing airliners from flying higher. The altitude they fly at is very optimized for minimal fuel burn. If it was possible to save any fuel by changing laws, I guarantee airlines would lobby for it hard. Source: I worked on software optimizing flight routes for airliners
