While I had headed to SeaTac to see the 21Air 767 arrive, I hung around for a couple of other arrivals. Delta operates a variety of long haul types into the airport and this includes A330s of the older and newer generations. First to arrive was an A330-300. A little while later, it was followed by an A330-900, the A330neo version. I thought I would try and get identical shots of both jets to see how much the engine and winglet changes showed up when looking at them in flight. Here are shots to compare the two types for you to make your own comparisons. I think the differences are there but they are not drastic.
