I would argue 25 is not too late at all. I didn't start until I was 27, and didn't even finish until I was 34 and still made it into the RHS of a jet. Many friends of mine older than me (up to 38) are in the same position.
I agree that the younger you are the better your chances, but 25 shouldn't be an issue in the current climate.
