Tohle je seznam "fyzickych" rozdílů mezi těmito, tak jak je zjistila EASA, když pro UK XL airways řešila, jak s těma typovkama.
The Boeing 737-900ER is 2.7m longer than the Operators current -800 fleet.
2 x MID emergency exits with integral slide fitted just aft the wing trailing
edge. The right exit has a cabin crew seat that must be manned.
The -900ER lift off attitude is 0.5° lower than the -800 series.
The -900ER is a performance category D (The -800 is performance category
C)
At Flap 30 settings the flare body angle between the -800 and -900ER is
negligible at 0.2° lower.
At Flap 40 settings the landing body attitude is 1° difference between the -800
and -900ER.
At Flap 40 settings the landing body attitude required is 1.6° difference
between the -900 and the -900ER.
At Flap 30 settings the landing body attitude required is 1° difference between
the -900 and the -900ER.
The emergency exit lighting at MID exits is type specific to the -900ER.

The mid exit door area heater system is a new feature on the -900ER.
The -900ER auto speed brake system differs to the –800.
The -900ER has differing speed brake load alleviations.
The -900ER is fitted with two tail skid protection devices which is similar to the
-800SFP variant.
The -900ER has performance limitations attached during tail skid retraction
mechanism failure.
The APU drain mast has been repositioned to account for the rear bulkhead
repositioning.
The leading edge slats are sealed during Take-off flaps settings 10, 15 and 25.
