In my eyes a 737-300 and a 737-700 almost look identical and I was wondering if anyone could tell me any of the major charictaristics between the two... (when viewing them at a glance!)
737-700's I know have how started to become common place having winglets, and these have helped lessen the confusion. But now as stated in another thread WN are glueing on winglets on to their 733's and this is not going to help.
Also I know some of the newer 737-700's no longer have the "Eyebrows" above the cockpit windows, but know many of the oldler ones still have them.
I am familiar with airlines like easyJet that painted the ailrons orange on their 737-700's, and could distinguish these between their 737-300 fleet.

18 foot greater wingspan (without winglets), 5 foot taller vertical stabilizer, and the wing is reshaped. When you see them next to each other, you can tell, and even flying in one by the window, you can tell just by looking out at the wing you are not on a NG. But just by looking from the distance, unless you've seen a lot of them and paid close attention, you won't know.
I just flew IAH-LAX and it was scheduled as a 73G but we were on a 733 instead. At the exit row, I could see how much shorter the wing was.
Of all the things to worry about... the Wookie has no pants.

The main features I use to tell the difference is the different wingtips of the -700 (more like a flat blade as opposed to the diamond shape of the -300), the lack of the continuation of the engine mount behind the wing in the -700 (this is the dead giveaway), and the way the engine mount doesn't extend over the front of the wing in the -700 the same way as it does in the -300.
Some of these cues aren't always easily visible, so it can indeed be very difficult.

The 733 is pretty easy to distinguish from the 73G if you are at the airport. All of the above mentioned ways are great, and I use one other when I'm a pax: The airleron is further inboard on the 73G than the 733, 734, or 735's. And the flaps. Just one look at the flaps either while spotting, or while on board will tell you which type it is.

If you are spotting you can use the above mentioned techniques, also the landing light configuration is different. Not sure if it was stated before. But the NG's main lights are mounted on the inward wing, and lower fuselage, where on the 300s they are on the inward wing, and outward flap canoe guides. If you are inside one...well, you should know when you walk through the door way, the door face itself is very different (it reminds me more of a 757) and when you enter the cabin, well just look at some pics, and the answer is as plain as day. I used to be based out of PHX, and when I walked past the WN gates I could easily tell which were which out of a row of them. Primarily by just looking at the wing tips in relevance to the ground, and of course the tail, and engines. In addition, the 700 is higher off the ground...its an all around more "beefy" machine.

Quoting AirTranTUS (Reply 4): The front of the cowling is also larger and more round on the 73G. The 733 is flat on the bottom while the 73G is more round.
The difference in engine cowlings when viewed from the front, and much taller tail, are the two most obvious differences to me. And if you happen to see an NG 737 next to any earlier 737 and have a front view of the full width of the wingspan, the much greater wingspan is also obvious.
Another difference is the longer main landing gear on the NG series that makes it seem to be sitting slightly higher at the rear than the front, while the -300 has a more level appearance.
There is one other difference if you have a close view of the nose/cockpit section. See Reply 30 in the following thread.

A few Exterior Differences would be as follows:-
The -300s have the Pitot Static tubes more Aft of the Radome.The -700s have the Pitot tubes more Fwd.
The -300 Powerplant has a Flat Inlet cowl lower side,unlike the -700.
The -300 is lower Landing gear than the -700
The -300 Wing root Leading edge is not streamlined to the Fuselage like the -700
The -300 TE Flap Transmission fairing is pointed unlike the Square tip on the -700
The -300 has Landing lights on the Outboard TE flap Fairings unlike the -700 where they are located ahead of the pack inlet under the Fuselage.
The -700 Powerplant has a Pointed strut from the Exhaust.
More detailed differences would only be noticable by Mx personnell so no point mentioning them.
