“…To ensure a high profit within a highly competitive market, most airlines fill their airplanes with the maximum number of passengers. This does not always contribute to optimized customer satisfaction (Nadadur & Parkinson, ). Thus, especially when traveling in economy class, passengers usually cannot expect a comfortable journey and have to find solutions to cope with the minimal living space available during their trip.…”

There is certainly room for economy-class travelers to make their trips more pleasant. A travel pillow might improve comfort. In this study, the comfort expectations and experience of travel pillows were examined. Comparing these 2 aspects indicated that it is not always possible to predict the comfort experience associated with a product based on a picture, and that there is a discrepancy between expected and experienced comfort. Experienced comfort is highest for travel pillows that restrict head movements in all directions in order to maintain a neutral posture. The results of this study also support earlier studies that suggested that discomfort experience can be predicted by observing the number of participants' in-seat movements; more movements result in higher experienced discomfort.

“…Besides the listed criteria, other researchers also investigated aircraft seating layout by measuring load/unload time of passengers [ 27–30 ]. Another study also tries to model an aircraft seat configuration by maximizing customer satisfaction and in-flight safety as well as being profitable for the airliners [ 31 ]. They utilized tools such as digital human models, layout optimization, and a profit-maximizing constraint to their model for an optimal floor plan.…”

BACKGROUND: Recent research indicated that an 18′′ ×30′′ aircraft seat resulted in nearly the same level of comfort as a 17′′ ×34′′ seat. However, it took less space in the floor plan. OBJECTIVES: This study explores seat layouts preferred by experts regarding different criteria. Those results of the experts are later compared to layouts produced by computational algorithms to evaluate the advantages of each method. METHODS: Eighty-eight experts in the field of aircraft interior were invited to make a floor plan of a part of a Boeing 777 aircraft where comfort was one of the main goals. Participants worked in groups of 3 and are given the freedom to design a section of the cabin between economy and first-class (5.87 m wide and 3.7 m long), where besides these two types of seats, an old business-class size seat of 20′′ ×36′′ was introduced as well for more flexibilities in design. Computational algorithms were also applied with the same inputs and constraints to generate layouts as a comparison. RESULTS: In total, 29 floor-plans were made, and these plans were analysed to compare against the complexity of the operations, the number of passengers on board, the revenue of the airline, and the width of the aisle. Results showed that 14 groups opted for the economy seats, while the rest utilized a hybrid setup where the business class seats were used in the configuration. These results are compared to the 126 computerized layouts generated. CONCLUSIONS: Among all layouts designed by experts, a combination of 28 18′′ ×30′′ seats and 20 17′′ ×34′′ seats had the highest potential revenue of US$21,984. This floor plan fits the regulations with an aisle width of 0.93 m. The computerized layout had a better outcome in maximizing profit of US$22,416 with 32 18′′ ×30′′ seats and 16 20′′ ×36′′ seats. However, the comfort of such results was to be explored as some seats were rotated 90 degrees.

“…17 The first comfort-based airline product feature is the aircraft interior layout and configuration, which influences the width and pitch of each seat, and thereby, determines the amount space that is available to each passenger. 31 Individual space in the aircraft appears to be the key comfort variable for passengers, but so too is the quality of the seating provided by the airline. Comfort is regarded as very important for passengers flying on long-haul intercontinental services, as well as for those flying on business and those travelling on leisure/holiday trips.…”
