To Pad or Not to Pad? A Note on the Schedule Padding Behavior of Airlines

ORCID Icon
 

ABSTRACT

This note provides a rationale for the current trend in airline schedule padding by studying the strategic behaviour of carriers that may decide whether or not to pad their flight beyond the optimal time necessary for flight completion. Using a structural demand and supply model for air travel, our results indicate that the positive price effects of schedule padding we observe are primarily driven by cost increases (inefficiency effect) rather than increases in markup (marketing effect).

2 The nested logit model has the following well-known predicted product share function: sj=expδj1σDg×Dg1σ1+g=1GDg1σ, where Dg=jGgexp(δj1σ) and Gg is the set of products belonging to group g.

3 We use the Herfindahl-Hirschman Index (HHI) to classify markets into competitive (HHI ≤ 0.25) and concentrated (HHI > 0.25) markets and followed the Department of Justice’s guidelines to determine the threshold HHI of 0.25. https://www.justice.gov/atr/herfindahl-hirschman-index.
