Revealed: What's wrong with this picture (teaser)

This one is from last month; various distractions and obligations have kept me from having the opportunity to finish what I started here. There are a number of little oddities about this photo; I noticed one that was the impetus for the original post, but then you guys pointed out several more. Among them: The U.S. aircraft registrations, the web addresses are different, and there are different types of tugs. There was some discussion in the comments about winglets; here's the same shot, considerably brightened, in which it can be seen that both of these A320s do, in fact, have winglets:

Another oddity that nobody commented on was the fact that both of these are A320s; most of Volaris' flights into LAX are in A319s like this one:

And now for the teaser part: Given the A319 photo, what's wrong with the A320s in the original shot? I promise it won't be another month for the answer; it's already written and scheduled to post 72 hours after this goes up, so think fast!

Shot of the day: Visiting dignitary

The United States is not the only nation to have an Air Force One. Korean Air Force One passed through LAX last week. Thanks again to CG, who took these shots in my absence.

What's wrong with this picture: Revealed

A bunch of sharp eyes out there - a number of you wrote in on this one!  This Singapore A380 has, as many of you noted, taxied beyond the entry point for runway 24 Right. The taxiway beyond that point is not rated for an A380, and so the only available course of action is for a tug to come out and push the aircraft back sufficiently for it to be able to negotiate the turn onto the runway.

This is not the first time that this has happened; I personally witnessed a very similar thing happen with another carrier earlier this year. Then, as in this case, the A380 pilots had to shut down their engines before the ground crew would approach and hook up the tug. Meanwhile, other aircraft on the taxiway behind have to depart from the intersection. If an intersection departure is not an option for them, then they have to wait for the tug to reposition the A380 so that it can then take the runway and depart. As you might imagine, this takes a little while to accomplish.

Thanks again to CG for catching this last week!

What's wrong with this picture?

It's time for everyone's favorite type of post, wherein I show you a photo with something odd taking place.  Today's edition is thanks to eagle-eyed CG, who caught this a few days ago on my day off.
So, What's wrong with this picture?

P.S.  -  The answers to the as-yet unanswered W3TP posts are still coming, but some of the guesses you guys are sending in are better than the actual thing!
