The documentation doesn't seem to specify exactly what is meant by 'success' in jQuery.ajax. Is it any 2xx code? Only 200?

From the source code:
if ( status >= 200 && status < 300 || status === 304 ) {
So any 2xx and under special circumstances 304 as well. 304 has some extra handling though, check the source for more info.

Angular js considers 304 a error, and triggers the error event – Lord Darth Vader Oct 05 '17 at 12:48

You'll find this in the done callback. A success is any status greater than or equal to 200 and less than 300. A notmodified (304) is also viewed as a success.
