Question Regarding 737s

Mon Feb 27, 2006 11:06 am

What are some of the main differences between the 737-300, 400, and 500 series? Just curious as I find it difficult to tell from outward appearance, thanks in advance.

Errm - length and consequently passenger capacity. I've always found them relatively easy to tell apart. The -400s have two overwing exits, so can be distinguished from the -300 and -500. The -500 is noticably shorter than the -300. Hope this helps  Smile

The 737-300 and 400 are similar, but the 400 is a bit longer, and it is actually a bit more rare.

If you look at the engines, it seems to me that each model has the engine a bit more rounded than the last, with the 300 the flattest.

The 737-500 is the shortest of the fleet.

The 737-700 is long, but the 800 is longer than 700 and 900 is longer than 800.

I know that the 800 and 900 have 2 exit doors over each side of the wing, and I'm not sure if the 700 does.

The last time I flew USAirways, I noticed that it looks like the registration of their 737s begins with the series number, such as a 737-300 has registration N305US for example. That may be flawed as I usually don't have much to do with that airline.

Look for a Continental 737-900. That thing is LONG
See, I knew American Eagle was first class all along!

Well, the -400 is the only of the 3 with 2 overwing emergency exits, and the -500 seems to normally have 8 windows between starboard front door and first gap in front of wing, whereas -300 seems to usually have 13, I believe.
That's what I have come up with as of now.
Or, WN -500s are N5**SW, WN -300s N3**WN/SW, or N6**WN/SW/AA ,AS -400s are N7**AS ,  
Also, UA -300s I have seen are N2**UA and N3**UA, and their -500s I have seen are N9**UA
