I used Google Trips to efficiently find important travel information such as flights, accomodation, things to do etc. The advantage of Google Trips was how it displayed information from multiple sources in an easy to use way.

I know that there is TripIt (which I used before Google Trips) but it doesn't come close in terms of ease of use and manual editing.

Google's suggested alternatives (Search and Maps) just don't seem like natural choices for me. I would prefer a standalone app where I can find flight information without the noise of search results or maps.
