Next to fuel costs, crew costs are the largest direct operating cost of airlines. Therefore much research has been devoted to the planning and scheduling of crews over the last thirty years. The planning and scheduling of crews is usually considered as two problems: the crew pairing problem and the crew assignment (rostering) problem. These problems are solved sequentially. In this paper we foc...

Sentiment mining has been commonly associated with the analysis of a text string to determine whether a corpus is of a negative or positive opinion. Recently, sentiment mining has been extended to address problems such as distinguishing objective from subjective propositions, and determining the sources and topics of different opinions expressed in textual data sets such as web blogs, tweets, m...

Strategic airline alliances are an increasingly common strategy for enhancing airline competitiveness and satisfying customer needs, especially in an era characterized by blurring industry boundaries, fastchanging technologies, and global integration. Airlines have been very active in utilizing this form of strategic development. However, the selection of a suitable partner for a strategic alli...

The purpose of this study is to examine the mechanism underpinning relationship between perceived supervisor support, organisational and service-oriented citizenship behaviour. data was collected from 250 flight attendants working in airline companies, structural equation model modelling using M-plus 7.0 employed test hypotheses. This research provides evidence for association psychological emp...

This paper presents several very interesting diagnostics for a comprehensive process-oriented validation of CCMs and CTMs in the upper troposphere/lower stratosphere (UTLS) and their application to the GMI CTM. It hence is a valuable contribution to ongoing validation activities within the different communities (e.g. QUANTIFY or CCMVal). However, the presentation and discussion of some diagnost...

Broadly defined, revenue management (RM) is the process of maximizing revenue from a fixed amount of perishable inventory using “market segmentation” and “demand management” techniques. While RM is not new (in fact it is as old as commerce, e.g., haggling in a market can be considered a form of RM), the theory and practice of RM have seen significant scientific and practical advances in the las...

The competitors in the airline industry often rely on pricing strategy to capture more sales as a main mean of competition. Thus, dynamic pricing is often utilized to maximize profit while allowing better pricing against competition at the same time. In order for dynamic pricing to be effective, airline company has to take in consideration both internal and external information. Tactical pricin...

Changes in the U.S. domestic airline route system have increased competition between international gateways. To assist in understanding this phenomenon, a system of models that predicts airline passenger flows resulting from different airline gateway hubbing strategies has been developed. The calibrated rnodels predict baseline passenger Mows quite accurately. The system was then used to projec...

The problem of adaptive stochastic airline seat inventory control lies at the heart of airline revenue management. This problem concerns the allocation of the finite seat inventory to the stochastic customer demand that occurs over time before the flight is scheduled to depart. The objective is to find the right combination of customers of various fare classes on the flight such that revenue is...
