Google is actively embracing PWA. Now Google Travel can run as a PWA app on both PCs and mobile phones, integrating three main features: Google Flights, Hotel Search and Trip. Now when users visit google.com/travel, Chrome jumps out of the option to install the app, placing shortcuts with custom icons on the desktop/mobile side.
After testing, themedia MSPowerUser said the PWA app provides features that are not particularly advanced, have no offline functionality, but provide faster access to Trips and so on. But it does provide notifications about your trip and can be opened and used like a local app. To use Google Travel on your desktop, visit google.com/travel, then click on Install plus in the address bar.
