Yes, you can. You can and should install Travelport Mobile Agent on all your mobile devices (tablets and smartphones) but note that you will only be able to be Signed On in one device at a time. However thanks to Continuity you can go from one device to another whenever you feel like it and continue from where you left. Learn more here.
You can use Travelport Mobile Agent in the device that suits you best at each moment.
If you would like to benefit from Travelport Mobile Agent's experience on your laptop or desktop, you may subscribe to use TTS Web Agent. It's available for all Travelport Mobile Agent's users. The same logic referred above applies to TTS Web Agent also.
