Then they can add A after the last number, which means it has the 6-bladed propeller. An ATR 72-212A is therefore a PW127 powered aircraft with a aft entrance door and 6-bladed props. A -201 will be PW124 powered, fore-entrance door and 4-bladed props.

-737-86Q
-737-85P
-737-86N
-737-808
-737-8K5
-737-8K2
I also know that this is the case for Jet2’s 757-200 fleet:
-757-236
-757-27B
-757-23A
-757-21B
I wondered, what is the difference between all these different varients and what does each stand for? Can anyone help me out, thanks in advance.

In 2016, Boeing announced that they would no longer apply customer codes to any aircraft produced after a certain point, which would lead to their designators being the "generic" type for the model. The codes were removed from the type certificates for each model with effect from the production line number shown below:Boeing 737 Next Generation: line number 6082
Further, customer codes have never been used for the 787 and 737 MAX, and will not be applied to the 777X either.
Boeing P-8 Poseidon: line number 6020
Boeing 747-8: line number 1534
Boeing 767: line number 1102
Boeing 777: line number 1422

That meant that an aircraft would forever more be stuck with an extra door or whatever the modification was for its entire life. The unique customer code would then indicate which specific variant/customer modification of the 737 it was.

But what trivia will aviation geeks argue over and try to use to attract mates in 10 or 20 years?
