What's the difference of these Ryanair 737 wings? Is one a newer model? Does it mean one of them is 737 max?

Seen this many times, there's also other type where there is no part pointing downwards, but inside airplane always say 737 800 only. Thanks

Which airport is this?

The max has got chevrons in its engine cowlings. So the one on the left it is.

Got it thanks.
So if you mention checking by the engine, could a non max have that wing too?

Only the max has that style of winglet. If only a single winglet that bends up, next gen. If it’s a double winglet with an obtuse angle, next gen (split scimitar). If it’s a double winglet with an acute angle then it’s a max

That was true for a long time but a couple carriers, notably United, have been putting these winglets on their NGs as well. It’s not common but it does happen. I used to rely on the winglets to visually identify Maxes at a distance but now I have to check the engines for shark teeth to be sure.

That would be news to me. United has done a ton of split scimitars but, to my knowledge as an Boeing engineer deeply involved on the 737, the wing on the Max and NG are too different to allow the new AT winglets (Max winglets) to be put on a NG.
That’s why I included the obtuse vs acute thing as the split scimitars are set at like 135 degrees apart while the ATs are like 80 degrees apart. Also the ATs top and bottom are roughly the same length while the bottom of the split scimitars are a bit shorter than the top

Ah, I see what you mean now. Maybe I’m just confusing the two, you’d certainly know more/better than I would; I’m just an enthusiastic amateur, I don’t work in aviation or anything.

It’s definitely takes a trained eye, took me a while to get used to the difference ha

Agreed, TUI fly NG 800s with the extended up and down winglets. Got a picture too!

Incorrect. You can retrofit the 737 NG with scimitar winglets. Ryanair is one of those that are doing it in fact https://corporate.ryanair.com/news/ryanair-cuts-carbon-emissions-by-165000-tonnes-with-winglet-retrofit/

No. Only the Max has those AT winglets. The NG on the right uses what they call Split Tip winglets.

As said, left is a MAX.
Ways to determine other than winglets:

Different genz
agha0013@reddit
one on the left is the MAX's split winglet (no blending)
On the right is the previous generation split scimitar found only on the NG series 737s
Before the split scimitar was the first generation blended winglet.
First gen blended winglets can be installed on older models than just the NGs, but the MAX split winglets is exclusive to the MAX

The aircraft on the left is a MAX with what Boeing calls AT winglets. The aircraft on the right is a NG with split scimitar winglets developed and installed by APB.

left one max, right one ng

The one to the left is a max
