It looks like A.I.R format is Amadeos propioretary:

from
http://www.travelworks.ca/Amadeus-Travelworks.pdf

The AMADEUS Interface level controls the format of the Interface records. At the time of
ticketing, the Amadeus Central System collects data from the PNR, TST, and your office profile
and generates the Accounting Interface Record or AIR. TravelWorks only supports AMADEUS
Interface level 207

It seems that format is desctribed in Amadeus document ICDTIRAIR207
which I'm unable to find after several days of googling.

I found only this document updates from which I got information about this format:

Probably I need to extract PNR record locator (http://en.wikipedia.org/wiki/Record_locator)
PNR stored in this file.

Maybe PNR record locator is stored in lines A- .. I- ... in my file.
How to extract it ?
PNR record locator can passed to https://www.checkmytrip.com/cmt/apf/cmtng/index?LANGUAGE=GB&SITE=NCMTNCMT
to get data.
