Hopper made a splash about 2 months ago for providing research data around things like When to fly to a place, what day of the week, what month of the year. (http://milepoint.com/forums/threads/using-data-to-determine-best-time-to-buy-and-fly.86960/ or http://milepoint.com/forums/threads/crunching-the-numbers-to-find-the-best-airfare.87117) http://www.hopper.com/flights/from-BOS/to-CDG/guide for example gives all that information. However, Hopper just launched what is being called the Flight Explorer. http://www.hopper.com/flights/feed/ What this is meant to do is to solve a real problem many people here have. I want to travel somewhere for a few days to get away, I don't really care where, where is a good choice? For example http://www.hopper.com/flights/feed/?utf8=✓&origin=city/NYC will show you sorted by price the cheapest price places to fly from new york city. However usually people have an idea they want to go somewhere vague. For example the Caribbean http://www.hopper.com/flights/feed/?utf8=✓&origin=city/NYC&destination=region/22wS Now these seem fairly simple. Lets look at something more advanced. How about someone who would consider leaving from boston, providence, new york city, or hartford to go to asia for 11-15 days in the winter of 2015. http://www.hopper.com/flights/feed/?utf8=✓&origin=city/NYC,airport/BOS,airport/PVD,airport/BDL&destination=region/2CIv&departure_day=&departure_flex=3:3&return_day=&return_flex=3:3&departure_month=winter-2015&stay=11-15&commit=Find Flights Also, instead of sorting by price, you can sort by most recent. This represents live shopping data from across the travel ecosystem. A feed that I keep open is http://www.hopper.com/flights/feed?departure_day=&departure_flex=3:3&destination=region/2CIv,region/26m5,region/25Cs,region/1uw0&origin=city/NYC,airport/BOS&return_day=&return_flex=3:3&deal_level=25&sort_by=recent&max_price=800&stay=&departure_month= This is "Give me all flights from Boston or New York to Europe/Asia/Oceana/Africa which are less than $800 sorted by recent" This means that as the day goes by I see Deals as they pop up to cool places. I held off on posting because I was a little nervous in acting like a shill. In the interest of disclosure, this is my day job and wrote a lot of the software in the links. Also, I am an engineer, and NOT an official representative and in no way is anything i write a reflection of a company policy or view. I wrote this post for two reasons. 1. I know that members of the community here will benfit from using it. 2. I know that members of the community here will likely have useful feedback. With that in mind if you have questions or feedback feel free to either reply or send me a message.
