LOL. the standing out difference from the 733/735 from the 734 are the overwing exits. 734s have 2 and 733/5 have 1.

735s are extremely short and cute.

733 - 1 overwing e/exit
735 - shorter version of 733 with 1 overwing e/exit
734 -Longer version of 733 with 2 overwing e/exits.

Telling the differance between a 734/738 or 735/737-7 now there the hard ones (unless they have blended winglets....

When I'm spotting I just look at the wing lengths or the rotating beacon lights. Also the NGs tend to be a little cleaner.  Smile/happy/getting dizzy

734 obvious...
733 = front and tail looks same length...
735 = front looks shorter than tail...

But it's all perception Big grin

The only way I have found to readily and positively differentiate a 735 from 733 (other than by the tail number) is to count the number of windows forward of the wing. All aircraft of these types that I have seen have 5 windows in front of the overwing emergency exit plug doors, forward of which there is a space without a window (a structural requirement), in front of which there are 6-8 windows on a 735, 9-11 on a 733. Thus, if there are 8 or fewer windows between the forward door and the space described, one can be as good as certain it's a 735 as surely as 9-11 windows means it's a 733.

The 734's two overwing emergency exit plug type doors on both sides, as noted in a previous reply, make it easy to be distinguished from a 735 or 735 which without exception have one per side.

737-400 is the longer one with 2 overwing exits.
737-300 has funky looking CFM egines with 1 overwing exits.
737-500 has less windows before the engines, and not as funky looking engines.

yup, -400 has two overwing exits. -300 only one. -500 is much shorter. then there are the -600/-700/-800/-900s. this is a little easier. the -900s are huge, you can't miss them. -800s are also larger than the -400s, but perhaps not noticeably so. same goes for the -700s relative to the -300s, and the -600s to the -500s. the key here is the next generation 737s have larger vertical stabilizers (read tails), and are slightly higher off the ground than the classics. not to mention they and look newer (some tell tale signs are to look for paint remains around the engines, doors, and also look at the build-up of brake dust/grease on the landing gears).

The easiest way to tell apart the Classics from NGs (apart from the tails) is to look at the pitot heads at the nose. The Classics have 2 pitot heads on each side set below the most aft window of the flightdeck while the NGs have 1 smaller head on each side below the second window.

Subtle differences in length, which tend to be discerned with practice, can distinguish 733 from 735, 736 from 73G and 738 from 739.

UNB732-the 733/734/735's engines are all the same. CFM56-3's. How can they possibly look more/less funky?

733 has one exit, the 735 is short and stubby, the 734 has 2 over wing exits and is just a slight bit longer than the -300

Not necessarily, You just have to know what to look for.

If you study the engines of the classics, and the NGs, you will see what I am talking about.

A couple other minor differences between the 'Classiscs' and the NG 737's:

1) The NG series have landing lights under the fuselage at the front of the main gear wheel wells.

2) The NG series, due to the redesigned wing, has a different shape to the landing light lens in the leading edge of the wing root. The Classics have the old square shaped lens (ala 707), whereas the NG's have more of a teardrop shaped lens.

Does anyone know if the NG 73's still have the landing lights that extend downward from the outboard TE flap fairings? Can't recall if the NG's still have them there or not.

It took A while for me to be able to tell the diffrence but I learned LoL....
You can tell A 737-400 apart from A 300/500 because of the length of the fuselage... A 500 is not really that easy to tell apart from the 300 but after A while you notice the fuselage of the 500 is slightly shorter then the 300.

The way I tell A 737 Classic from A NG 737 is the way the engine is shaped...

The NG 737 Engines are more round the 737 Classic engines are sort of str8 at the bottom.

Also, the 733, 734, and 735 have a squared off fairing close to the fuselage as seen here:

733 is easy to tell. It's very short and stubby.
734 is quite a bit longer than the 733 and stands out because of this
735 dunno, never seen one before but looks similar to a 733 from the photos
