I love these new services that help you save money!
I found out about this new site called TripDelta.
The site was built by a team of mathematicians who traveled to more than 100 countries to find the best airports to connect you to where you want to go. For example, if you’re flying from San Francisco to London, tripdelta finds the cheapest route will be from Oakland to Los Angeles and then from LAX to London (LGW). Kayak simply has you go from SFO, which costs $193 more.
Here is a link to check it out.
