This thread may be of interest to some of you. I'll be tracking Delta and Northwest flights to see if the "Northwest way" of flying will come over to Delta.

Basically, Northwest tends to fly low if they can avoid turbulence, or take the long way around an area. I haven't noticed Delta doing the same. So in this thread, I'll be posting some observations of Delta and Northwest flights (while the two are still distinct).

If you look through the blog, you'll have a better idea of what I mean.
