All good answers, have you had a look at this for passing messages along.
TempData and Session arent the best idea for RESTful architectures as most sessions are stored in memory. So when you want to use a server farm, the users session would exist on one server while their next request could be sent to another server.
That being said have a look at this use of TempData for passing messages here.

Mabye this could be adapted to use a query string approach if used only for redirect to another page alerts.
