GLMZ's airspace above the 80-meter line is formally divided into managed transit corridors under the Meridian Aerial Infrastructure Compact of 2163, a governance document that effectively privatized the city's low-altitude sky. The Compact established three corridor tiers: Executive Air (above 300 meters), Commercial Logistics (80-300 meters), and a nominally reserved Public Safety band used by MSA, fire response, and medical evacuation units. There is no public passenger aerial transit tier. The sky, in GLMZ, is for cargo and the wealthy.

Executive Air is the operational domain of Harmon Logistics' personal aerial vehicle service and its two smaller competitors, Stratos Charter and VertiFly Premium. These operators provide point-to-point aerial transit — typically between corporate tower landing pads and regional transport nodes — for Tier-One passengers and corporate executives. A single-passenger Harmon aerial pod trip from the Caldor Tower complex to Meridian North Regional Station costs approximately 180 CredUnits, roughly 60 times the equivalent Spine Corridor fare. The market is small by volume but significant by revenue: approximately 12,000 Executive Air trips occur daily across the megacity. The passengers on these vehicles are disproportionately the people who make infrastructure policy, which critics argue is a direct causal factor in the chronic underinvestment in ground-level and vertical transit.

The Commercial Logistics corridor is vastly more active — an estimated 280,000 autonomous cargo drone transits occur daily, carrying everything from pharmaceutical deliveries to corporate document packages to restaurant supply runs. The logistics corridor is where the aerial infrastructure visibly affects daily life for ordinary residents, primarily as an ambient noise and shadow presence rather than a mobility resource. The drone density over mid-tier commercial districts during business hours is high enough that the sky is rarely free of the characteristic mid-frequency hum of delivery rotors. In 2171, a Caldor Logistics drone suffered a guidance failure over the Ashford district and struck a residential balcony, killing one person. The subsequent liability settlement was sealed under a corporate confidentiality agreement.

The absence of public aerial transit is a deliberate policy outcome rather than a technical limitation. Aerial transit infrastructure studies commissioned in 2167 and 2169 by the Meridian Infrastructure Council both concluded that a public aerial bus network operating in the 80-150 meter band was technically feasible and would meaningfully reduce ground-level congestion. Both studies were shelved following lobbying from Velorant Systems, which identified aerial public transit as a competitive threat to Spine Corridor ridership revenue. The studies are not publicly available but have been partially reproduced in unlicensed mesh journalism. Meanwhile, activists in sub-street communities have noted the particular cruelty of an aerial infrastructure that passes directly over their neighborhoods while offering them nothing.
