I know this is a pretty rare aircraft that can be spotted on our sky (I think only KLM, Korean Air and Alaska Airlines owe them, alltogether 42?), but I would die for a pretty nice model fo b739 for FS2004. I've been looking for this for almost a year, and what I found until now is either AI Traffic textures or corrupt or uncompleted files (with no engines funs for example). Has anyone have any good source of .zip file to download of this beauty? (alaska air. would be the best)
I don't know about freeware, but PMDG has the 800 and 900 as and addition to their 737NG package (600 & 700) Of course to use the additional models you have to have the NG package, so it gets a bit pricey.
If you own the PMDG there are a few freeware textures available for the -900 ➡ http://library.avsim.net/search.php?SearchTerm=b737-900&CatID=root&Go=Search
