It used to exist as its own separate app called "Get The Flight Out" but for some reason we removed it from the app store. We also had a feature devoted to something similar for "flexible watching" but it never got much engagement and it didn't warrant the infrastructure cost it required to keep up.
It is very rare that an app will provide more value than a website. And most of the time when it does, it's just because the website is shit, and they spent more time on the app. But if they focused on the website, it would be way better than whatever experience the app is giving you.
Here's something to think about: would you download and install a desktop application for every random website you come across? No? Then why do it on your phone? People must just make better websites.
Also, it allows me to express my disdain at such a decision and if enough other people did too, said engineer has the ability to go up the flagpole and inform the decision makers that there are many people who are displeased at their decision.
So the smart thing to do (at least in our opinion) was to not even play the search engine advertising game and focus on building mobile apps that users will come back to after using. We tend to see really high retention rates with users because they like the experience and we don't have to pay for the ad impression every time they feel like searching for travel destinations.
