ABSTRACT
In this paper, we examine the U.S. domestic airline
network. Using an exhaustive definition of the airline
network and a cross-section pooled time series
dataset for 35 consecutive quarters covering
1995:Q1 to 2003:Q3, we analyzed domestic scheduled
air transportation. Results suggest the existence
of increased vertical disintegration of market segments
following the events of September 11, 2001
(9/11). The effects of 9/11 have affected all network
classes, with the largest impact on the point-to-point
variants. The expansion of Southwest Airlines
affected all variants of the network positively, with a
proportionately larger impact on the point-to-point
over the hub-and-spoke variants. The results of this
study are expected to help inform both operational
decisionmaking and policymaking. Results may also
be useful to manufacturers in projecting the size and
mix of the aircraft fleet that are expected to be compatible
with the evolving network.
