However, to ATL787's point, you can calc figures like this -
and while Wikipedia shows 160 mill pax for DL in 2010, the BTS figures actually show fewer (and I think are probably more accurate).

for 2010:
DL bag fees $952.250 mill
DL pax 110,925,000
= $8.585 DL bag $/pax

AA bag fees $580.663 mill
AA pax 86,129,000
= $6.742 AA bag $/pax

DL flts 766,906
$1241.678 DL bag $ / flt

AA flts 619,643
$937.0928 AA bag $ / flt

One might conclude from this data that Delta has been more efficient in monetizing checked bags.
