In an attempt to better compete with low-cost airlines, major air carriers like American Airlines, Delta and United have been rolling out “basic” economy fares – no-frills fares that charge fees for amenities that would otherwise come standard, like seat assignments or the right to use the overhead bin space, for example. But this unbundling has also made it difficult for customers to price the true cost of their trip, which is where the travel app Hopper now aims to help. Hopper has long since been one of the more useful trip planning applications on the market, with a variety of features that help you find the lowest priced airfare. Its forecasting software tracks airlines’ ever-changing ticket prices in order to predict prices and alert you when it’s the best time to buy a ticket. In December, when Hopper announced $61 million in Series C funding, Hopper’s users had tracked 18 million trips on its app, which was seeing over a million installs per month. Today, Hopper tells TechCrunch that it has seen more than 12 million installs since its 2015 debut, users have tracked over 27 million trips, and have booked over $300 million worth of flights. It’s now selling over $1 million worth of flights per day. Get the full story at TechCrunch
