The aircraft pictured is still relatively new. It was delivered to the airline in December 2014. Speaking of picture, it was just great timing on my part as far as centering the Mandalay Bay resort within the image.

The A321E is similar to a standard A321, except for an updated interior and blended winglets.

I also want to mention that the registration, N129AA, was previously used to identify an American Airlines DC-10-10. That aircraft, and many others, was transferred to Hawaiian Airlines. By 2003, all Hawaiian Air DC-10s were WFU (withdrawn from use).
