In a recent
thread, I showed how you can specify the
booking code in ITA.
Here's another unpublished feature of the
ITA software. This one allows you to specify the
fare basis code.
I'm no expert on fare basis codes, but I suspect this will be useful to some FTers.
The extensions to the itasoftware routing language are accessed by postpending commands after a '/'. There's a wide set of commands available, but there's no description of them available on the ITA web site. Unfortunately, each command applies only to one part of the trip, so they must usually be entered in each box.
CONSTRAINING FARE BASIS CODES:
Command is: "f CC.AAA+BBB.FFFFF" or "f CC.AAA+BBB.FFFFF|..."
where CC is carrier code, AAA and BBB are fare origin
and destination city, FFFFF is fare basis code
Ex: fare only with NW BOS-LAX YUP fares:
from: BOS::/ f nw.bos+lax.yup
to : LAX::/ f nw.bos+lax.yup
Ex: fare with either YUP or F fares on any airline and between any
points:
from: BOS::/ f ..yup|..f
to : LAX::/ f ..yup|..f
Ex: fare using only "through" fares
from: BOS::/ f .bos+lax.
to : LAX::/ f .bos+lax.
Ex: fare using only NW YUP fares or UA F fares:
from: BOS::/ f nw..yup|ua..f
to : LAX::/ f nw..yup|ua..f
More to come…
