Yapta Overview

Yapta is a browser bookmarklet used to track the fares on your upcoming flights. After bookmarking any number of different flights at different sites, you can then go back to Yapta to compare them amongst each other.
If the fare increases or decreases before you make a purchase, that will be reflected on the Yapta site. If you make a purchase by clicking through to the airline or travel site from Yapta, they’ll continue to monitor the price. If it falls, they’ll ping you and suggest you contact the airline for a refund or flight coupon
