Data and Methodology

This report is based on 1,957,399 round-trip flight prices from crowd-sourced airfare searches made between November 11, 2017 and November 18, 2017. We’ve included all trips that were shops less than 6 months before the departure that include a Saturday night stay.

Our data is drawn from Hopper’s combined feed of Global Distribution System (GDS) data sources which includes about 10 million flight price queries per day, containing about one billion individual trips per day. Demand is represented as the number of queries not actual ticket purchases, and is calibrated across all GDS sources for each market. Lowest fare, or deal fare, is represented by the 10th percentile prices. For example if the 10th percentile price is $800 dollars it means that only 10% of trips are priced at or below this price.

Prices and popularity by date are determined by aggregating all flights that depart before and return after the date in question. Prices by date are 10th percentile prices of such flights. Popularity by date factors out the overall advance purchase distribution, as search rates naturally increase close to departure, in order to highlight long term patterns.
