What do these stages mean? (Pending, Available, etc.)

When you submit an auto check-in, you can see different stages:

1. Pending - when you have submitted your check-in and your request is in the queue.
2. Available in X hours - when we know the time when we will check-in.
3. Suspended - you need to enter additional information (either you will receive an email about it, or tap this status to fill in the missing information).
4. Canceled - the check-in has been canceled.
5. Failed - the check-in was not completed.
