Wheelchair Accessible Seat passengers are given an emergency sling such as ADAPTS Portable Transfer Sling and further emergency protocols. IMPACT Five major U.S. airlines have 262 A321 models in service. Assuming 50% of airlines implement the accessible seat, government subsidies and tax deductions can reward Figure 3: ADAPTS Portable Transfer Sling, https://www.adapts.org/ airlines who implement accessible seats therefore enabling fair ticket pricing that keeps the average domestic flight cost of $359. With a conservative estimate, an Acknowledgements A321 does 2 flights/day, 365 days/year, the opportunity cost of the accessible seat is: Dr. Patricia Buchanan - University of Washington (131 planes x 2 flights/day) x 365 days/year x $359/ticket = $34, 331,170/year Glenn Johnson - Collins Aerospace When an organization reaches out to diverse customers, their connection to diversity Malcolm & Deborah Cumming and inclusion will tie into their brand and business performance..
