Why are same aircraft types loaded differently

Example....Thompson 757-200 mainly 120 in hold 3, 100 in hold 4, and remainder in hold 2

Thomas cook 757-200 mainly 80 in hold 2, 120 in 3, and remainder in 4

Jet 2 757-200 STUFF AS MUCH AS POSSIBLE IN 3+4.

Maybe the standard loading plan refects the degree of trim required by each airline.

as a 757-200 freight operator, we adopted a further aft C of G trim for economy about a year ago.

also down to the dispatcher... ive seen A319's arrive with all the bags in hold 5, yet they get loaded up with all the bags into hold 4... even though its similar PAX and bags/cargo figure

cabin lay-out might be different, and thus resulting in a different basic index.

I believe Ryanair actually prefer a nosey trim! I expected them to prefer an aft cg for economy/efficiency however a friend who flies for them says its due to speed stability issues when on ground.

Depends on the carrier i assume.
TCX for me is 80 hold 2 100 hold 3 and remainder bags, buggys etc in hold 4.
I have seen A320's come in and they dont use the forward holds at all. 3,4 and 5 are filled as much as possible.

Either as per carrier recommendations or for optimum fuel trim.

And for me there is no such thing as "standard" loading, every flight can be different, you can have an assummed load based on a full flight and thats about it as even the destination or time of flight can be a factor such as golf clubs on faro flights or ski equipment or flights business type flights that may be full of people but very little baggage

There are a number of different reasons for this principally
1. Aircraft cabin configuration where are the galleys located, seating configuration etc.
2. Airline preference
a. Fuel saving, aft C of G usually saves fuel although the actual saving varies by aircraft type
b. Speed of turnround, the operator might prioritise a quick turnround over fuel saving this may necessitate use of but forward and rear holds so two crews can load the aircraft.
c. Loading restraints may mean that cargo can only be loaded in certain locations.
d. Seasonal loads like Skis

I can't speak for the others but at Jet2 its company policy to trim the aircraft back heavy for economy savings.

From a pax perspective the online check in system allocates pax in the aft section of the aircraft automatically, but when its a light flight i.e B733 on uk domestics, having 40 pax in bay C and 10 pax in bay A causes some right promblems!
