This section, will focus more on the supply side of theproduct, by examining the product decisions that airlinesmust take. In doing so, they fact a dilemma. Theypresumably wish to offer a product which is as attractive aspossible to the customer.However, an attractive product will often be an expensiveone to produce. Therefore, decisions must often be basedon a complex tradeoff between product quality andproduction costs. The logic is more seats equal to morerevenue but less comfort for passengers5.3 Fleet & Schedules-Related Product Features5.3.1 Cabin Configuration and Classes of ServiceThe principle of trading off product quality againstproduction costs is well-illustrated by this first area ofdecision-making. An airline seeking the lowest costs ofoperation will configure its aircraft in a single class, and willplace as many seats as possible in each plane.Safety considerations will give an absolute limit. Thesewill reflect both the structural capabilities of the aircraftand the need to meet standards for emergency evacuationsOther structures , especially on long haul flights , wouldreduce further the number of seats which are , numbers oftoilets and galleys as well as other aircrafts features .5.3.1 Cabin Configuration and Classes of ServiceDecisions about basic seating comfort standards have avery significant impact on unit cost levels. For example,leisure-orientated airlines will usually place 235 seats into oneof their most commonly-used aircraft, the Boeing 757. Thisresults from a mix of seats at 28 and 29 inch seat pitches.An aircraft seat pitch is the space between a point on oneseat and the same point on the seat in front of it .Raising the seat pitch to 33 inches − typically used byscheduled airlines − reduces the number of seats that can beplaced in the same aircraft to around 180. Thus a decisionabout cabin comfort can affect unit costs by 30%.5.3.1 Cabin Configuration and Classes of ServiceBoeing 7575.3.1 Cabin Configuration and Classes of ServiceSeat WidthSeat PitchAisle Width5.3.1 Cabin Configuration and Classes of ServiceAn airline whose marketing strategy is based ontargeting both the business and leisure traveller cannot relyon a cabin configuration aimed at producing the lowestoperating costs.Instead, they must develop a multiproduct philosophy,one of the manifestations of which is the need to havedifferent classes of service on board their aircraft. The costimplications of doing so are substantial, and are becominggreater all the time5.3.1 Cabin Configuration and Classes of ServiceTHAI A380 Cabin Lay-out5.3.1 Cabin Configuration and Classes of ServiceBusiness Class seats can be categorizedby one of the following descriptions:Recliner Seats:These seats do not offerthe significant recline of the Lie-flat andFlat Bed Seats, but still offer excellentspace and comfort.Angle Lie-Flat Seats:While airlines oftenmarket these seats as having 180degrees of recline, in their fully reclinedposition they are slightly angled and donot lay completely horizontal.Passengers often find these seats to beextremely comfortable for relaxing andworking, but not conducive to sleepwhen in the fully reclined positionbecause of the awkward angle.Flat Bed Seats:When fully reclined, theseseats are completely horizontal, creatinga bed that is fully flat. These seats alwaysreceive high accolades for beingcomfortable both as seats and beds.
