Tripdelta Finds Cheaper Flights on “secret” Routes From Airports
Flying through major airline hubs can make your travel more expensive than it should be. Tripdelta finds hidden airports that can save up to 90% on a standard route.
The site was created by a team of mathematicians who have traveled to over 100 countries to find the best airports to help you get where you want. For example, if you are flying from San Francisco to London, tripdelta will find that the cheapest route will be from Oakland to Los Angeles and then Los Angeles to London (LGW). The kayak will just get you going from SFO, which costs $ 193 more.
Tripdelta is currently best suited for one-way flights and additional charges may apply for multiple connections. However, if you are looking for the cheapest flight, this is a good place to start.
