Wrote a little python… to extract the monthly operation results from airlines, and calculated load factor change, RPM change and ASM change.
- RPM = Revenue passenger miles, and its percentage change year-over-year
- ASM = Available seat miles, its percentage change year-over-year
- Load factor = RPM / ASM, its change year-over-year
- RPM_g = RPM(t) / RPM (t-12) – 1
- ASM_g = ASM(t) / ASM (t-12) – 1
I did Alaska and Southwest tonight and will add more…
