Hi guys,

I was graphing fuel exp per ASK (y-axis) vs avg kilometers flown (x-axis) for both PGSUS AND THY. There's a strong negative correlation for PGSUS whereas a strong positive correlation for THY. What does that tell? Is it about being a LCC?
I thought the usual one is a negative correlation.

What do you think? Thanks in advance.

Try comparing other LCC (vs. PGSUS) and legacy (vs. THY). IMHO looking at two different airlines will not give you proper output (value-added).

Quoting ptahturan88 (Thread starter):
I thought the usual one is a negative correlation.

Why should the fuel expense decline with increased avg. km flown fuel?

I would also look at ASKM/RSKM vs. Fuel Exp. ASK (does/what is the relationship between the fuel expense increases vs. (increased) ASKM and RSKM).

OK, what aircraft ? 737NGs I assume?
It does have to do with:
1. Their speed/cost index policy
2. Their 1st choice altitude policy
3. Payloads
4. Holding & Alternate policy

That, gives you the fuel burn in kg/km...
Now, then we go to:
5. Where and who do they buy fuel from? (vendor pricing policy)
6. Do they conduct tankering (this reflects on effects of #3 and #4)
(and the list goes on)

If this is not aircraft type specific, THY's diverse fleet would give that positive correlation instead of a negative one, as with widebodies, the difference in fuel burn per hour changes a lot throughout the whole flyable grossweight change... etc etc etc...

When losing situational awareness, pray Cumulus Granitus isn't nearby !
