From our work here, we suggested changes to many U.S. routes and schedules to reduce carbon emissions. Our letter of 21 September 2016 (the latest in a series) to the Administrator, FAA Michael Huerta stated “The global impact of greenhouse gas emissions from aviation are recognized and you are seeking a solution. Jet operations at busy airports also create sub-micron particulate concentrations, a recognized public health hazard.
“Currently, city-hub-city routes add hundreds of airport operations and thousands of air miles daily compared to 2005. However, more passengers reached their final destination in 2005 than in 2015. A comparison of 2005 (more operations and passenger boardings) to 2015 will show higher fares, more pollution, more safety risk management and facilities costs, and more carbon emissions (per operation).
“We see few or no public benefits from peak-hour congestion at U.S. airports. The public has a right to know if current policies and plans are worth the high costs and the health risks. Forecasted passenger capacity needs are annual; operational hours, daily: high runway use for a few hours per day is beyond need and too costly.”
The Forum identified serious uncertainties regarding Minneapolis-St. Paul International Airport (MSP); these safety and capacity issues are typical around ‘metro-plexus’ (multiple airports in a densely populated area) and many hubs at peak-hours are used as if pending NextGen and PBN (precision GPS navigation) ATC and avionics were actually deployed. The air traffic control procedures under these conditions are a ‘safety risk’ managed in real-time by FAA, airport by airport. A re-alignment of the national airspace system shortening city-hub-city routes would reduce fuel consumption and GHG emissions far more than a miles-per-gallon standard.
The routes and profiles in use at hubs to increase air operations per hour, however, often increase per-flight safety risks as well as public health risks. Changes resulting from airline mergers exceeded the Next Gen design, tripled the projected cost and extended deployment by at least a decade.
The letter formalized prior communications in which SMAAC argued that:
a)   planned annual capacity differs from arrival-acceptances per hour or runway-use ‘efficiency’ and high peak-hour operations are subject to environmental review and capacity agreements with the airport sponsor;
b)   the FAA has the authority and the duty to protect the public health and welfare by reducing GHG and carbon emissions and the authority and the duty to limit flight routed and schedules for safety in flight and at airports.

Several people asked for copies of our letter to FAA Administrator Huerta.  The distribution list is temporarily confidential, and we have posted articles relating a light-cap at MSP to changes in national hubs-and-spokes routes.  The FAA priorities for Next Gen at airports deployments are ever-changing because schedules and runway use (capacity) changes are costly and environmentally controversial.

So I didn't mean "Share our letter" literally.  I meant share our IDEA for re-planning the national route-support to relieve congestion at hub airports by using surplus runway capacity and already supported routes at more connecting hubs.
