Africa - JNB to JFK Flt A340-600

We are on this flt later this year. I noticed the flt to IAD leaves over 2 hrs earlier but only gets to IAD about 15 minutes earlier.

Does the JNB-JFK flight not stop over in Dakar for refuel? Its a A340-600 vs the IAD flt of A340-300

Thanks all.

Yes, the JFK flight is non-stop. I think SAA removed the stop about a year ago. :)
