Prices for the same flight change substantially depending on the time of purchase. This paper uses a unique dataset with round-the-clock posted fares to document significant within-day price variation. Labeling time-variation as discriminatory is difficult because the cost of an unsold airline...

In this study, we document and analyze price-offer curves (the dynamics of offered prices as the departure date approaches) for 105 specific round trip itineraries on 50 busy US routes. The data were collected from the three leading on-line travel agents' web-sites. We exploit across-route...

We use unique data sets with round-the-clock posted fares and a regression discontinuity design to identify price discrimination in advance-purchase discounts. Price discrimination increases fares by 14% between two and one week before departure, and by 7.6% between three and two weeks to...
