Here is one I would do if I had a bottomless wallet (which I don't). $65 Cad incl shipping on eBay - rather a lot for a small model. I have always liked the DC-9/MD80 series. There is something friendly looking about that slightly longer, pointier nose. Like Snoopy. Anyway, this is a lively SAS scheme. Maybe someone else would like to take it on. Decals are in the kit, apparently.
To further answer Pedro's inquiry @holzhamer, I empathize as an airliner newbie. I found a lot of ideas by following the Wikipedia entry Erik cites - which shows a pic of each type in SAS service. I then Googled each type that interested me with something like "A320 SAS" for photos of the real thing or "A320 SAS 1/144" for a possible model. Doing the search with Google images or video helped and led me to many builds, which often suggest paints and decals to use. I did something similar on eBay to check availability and prices of kits. Found a few more that way that Google hadn't shown me. In the end, I had a lot of fun and realized airliners would be a neat quick build experience which might also not be too expensive, depending on the kit.
Here is a cool website with excellent model builds. The SEARCH function allows you to search for SAS airliner model builds.

I hope this helps.
