This map is based on round-trip flight prices from crowd-sourced airfare searches made between December 16, 2017 and December 17, 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 each 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.
