The record includes 16 papers that explore sketch models for air transport demand estimation, supporting aircraft manufacturers to systematically formulate and implement sustainable development strategies, mixed logit analysis of international airline choice, conceptual framework for collecting online airline pricing data, quantifying the relationship between airline load factors and flight cancellation trends, and a modeling framework for airline competition in the U.S. domestic network. This issue of the TRR also examines depeaking strategies for improving airport ground operations productivity at midsize hubs, a modeling framework for airport terminal planning and performance evaluation, route choice control of automated baggage handling systems, value of flight cancellation and cancellation decision modeling, resource allocation in flow-constrained areas, prioritizing aircraft operations at congested airports, design of ground delay programs, considering hydroplaning in runway geometric design, characterizing the distribution of safety occurrences in aviation, and analysis of the workload of training captains.
