Airplanes with winglets

Is it true that all US airways a319, a320, a321s have winglets on them? I no that US airways have winglets installed on their 757s and 767s but im not sure about this.

All A320 series aircraft have wingtip fences.

does tht include the a319 and a321? it this for all of them or just US airways planes

Yes, A318-A321.

Also, US Airways does not have winglets on their 767’s.

All aircraft use the wingtip fence except the A330 and A340.
