Photo Detective Help: 2006 SEA-ANC Flight

In July of 2006 I took an AS flight from SEA to ANC, and I'm trying to recall a few particular details of the flight. I found a few pics that I snapped from the airplane window, shown below. Here's the challenge: Tell me everything that you can deduce from the photos. There is a bit of wing showing, and I think it looks like a 737-NG wing. Am I right? That's important, because I'm trying to figure out if I was on a 734 or something newer. For those who are more familiar with this route, is there anything distinguishing about the landscape to indicate the approximate location? The timestamp on the photos shows they were all taken in rapid succession.
Thanks for your help. I know this is a tough one.

That is a 737NG. It looks like a -800 from the lack of vortex generators. The flap "canoes" are squared off at the end, on the 734, they come to a sharp point. Also,the wingtip position light is what is used on the NG.

I noticed that when comparing to other photos, and is why I assumed it was NG. Thanks for confirming!

 Quoting DL_Mech (Reply 1):That is a 737NG. It looks like a -800 from the lack of vortex generators.

Could it be a -900 (non-ER)? When I look at the old schedules, the flights I think I was most likely on are either 734 or 739.

I didn't know if AS had -900s in 2006, so I guess it could be. I know that the -700s have a lot of vortex generators near the leading edge.

BTW, props for spelling "TriStar" correctly (with a capital "S") on the other post.

EDIT: I thought -700s had more vortex generators, but looking at photos, I think I'm wrong. Here is a -500:

Does the time-stamp have an accurate day and time? If so we might be able to figure out everything about that flight.

You may have been. The old schedules show primarily 734s, 73Gs, 739s, and MD-80s in July 2006. I'm checking a couple random days in early July on the BTS website, and neither day shows a 738. Only later in the month did a few start showing up. In fact, AS was just receiving 738s back then and didn't have many in the fleet yet. It's obviously not an MD. The wing is from an NG, so there goes the 734. So you were probably on a 73G or 739.

Using Google Earth, it looks to me like you're flying over Vancouver Island at around 6-7PM. It's the only piece of land that looks right.

RE: Photo Detective Help: 2006 SEA-ANC Flight

Very unlikely go be an 800, more likely 700 or 900. The 900s frequently fly this route.
If you have never designed an airplane part before, let the real designers do the work!

The date is right. July 1st. But the timestamp is questionable. It says 17:55, but I'm not confident that it's right. I was living in Utah at the time, so most likely mountain time, but I'm not positive.

This was a fishing trip with my dad and brothers. The other bit of data that recently came to my memory is the fact that my oldest brother was on the non-stop ATL-ANC flight, and we were scheduled to arrive at about the same time. Based on the BTS data I looked up, the daily DL flight from ATL was scheduled to land at 20:30 in ANC. So everything is pointing to me being on AS85, which was scheduled to land at 20:34, and operated by a 739. That flight left SEA at 18:29 PDT (slightly delayed according to the BTS data). So if my timestamp of 17:55 is correct for Utah/MDT, then is would be about 25 minutes after takeoff, and your idea of Vancouver Island would be just right. Would the mountains in that area have that much snow in early July?

Oops. I got that backwards. 18:29 PDT would be 19:29 MDT, so the timestamp would indicate that the camera was already on Alaska time if the rest of the information is correct. So that's the confusing part--I can't believe that I proactively changed my camera's clock. I never do that. There was another flight roughly 2 hours earlier, where the timestamp would make more sense, but that one appears to have been on a 734, and wouldn't have arrived in ANC at the same time as my brother's flight from ATL. For now, I'll assume that my camera was in fact set to Alaska time, but I'm not sure how that happened. There are a few other pictures from the trip that seem to confirm that the camera time was at least within 30 minutes of being correct for Alaska.
Thanks to everyone for your help. I think we can put this one to rest for now.

Excellent. I looked at all the possible flights without seeing your conclusion, and to me the only one that made sense as well is flight 85 operated by N307AS. The sun angle lines up with you being over Vancouver Island at about 19:00 local. The other earlier flight on a 739 left at 15:56 local, so the only way you'd have the sun over the wing in that area is very late in the flight. So with that and the story about your brother's flight, I'd be pretty confident that #85 was the flight you were on.

 Quoting redzeppelin (Reply 6):Would the mountains in that area have that much snow in early July?

I've never been over that area, but I looked up pictures and saw quite a bit of snow yet in June. So the first day of July seems like it could have plenty of white yet at the highest peaks (which is where the terrain looks closest to your picture too). I looked at Google Earth along the entire route length, and no other area looks like that. The other pieces of land either have glacier-carved valleys, are too small, ocean is visible, etc.
