Reserved or not reserved is just a billing convenience. There is no concept of a particular instance being reserved or not.

So for example if you have two instances and have purchased on reserved instance and one is 'on demand', you can delete either one of them, and one of them is still reserved.

To check your reserved instances:

  1. login to your aws console.
  2. Go to EC2 management page.
  3. Expand Instances
  4. Click on Reserved Instances

Here you can see all your available reserved instances if available, else "You do not have any Reserved Instances." is displayed.
