Yatra Desktop Buddy is a small free desktop application from yatra based on adobe air platform, that means you can run this application any where on any OS including Linux, Mac OS or Windows. The only thing you require to run this application is to install adobe air run time environment.
As shown in the image above you can do flight booking, see the airfare calendar, check out your booking with your yatra account and get trains availability and book tickets.
If you have a yatra account, you can login to your account with this application and view the status of your flight bookings and train bookings you had done before. [ as shown in the image below ]
I am finding it quite useful, its lets you do booking and see the availability of flights quickly. I hope you will like it too
