From a quick search on Google, assuming there's no winds or anything like that, such an aircraft would be capable of flying from LAX to NRT non-stop.

This could make such flights more comfortable to operate for these budget airlines. If, and let's go with if, the A321XLR manages 9,000km of range when it's actually made, then you're possibly looking at trans-pacific flights from smaller West Coast US airports to smaller Japanese airports.
From Seattle, things get better, and you can end up with flights being able to reach South Korea from there.
If Anchorage becomes a major hub, even it is a great location, with the XLR being able to get to pretty much all of China from there, including Hong Kong. It can also get to the Phillipines.
The A321XLR will be trans-pacific capable. Australia will be out of the question, but Asia will be more than within range.
Even the current existing A321LR is capable of going up to 9,300km range with a low density cabin (think along the lines of the existing A318 cabin for British Airway's LCY-JFK route). Imagine what an A321XLR in a low density cabin could achieve?
