AL-Pro supports the concept of "packages" which are products with multiple components. Below is a screen shot of the Product Availability & Event Assignment form from AL-Pro.
To get a list of products on multi component packages for the highlighted base "Scenic" you can use
als_get_package_products.cgi?base=8
which returns XML with the productcode
<row productcode="189" productname="Canyon Connoisseur SBG-5" basename="Scenic Airlines" basecode="8"/>
Using the productcode of 189 we can then ask for "Offerings"
als_get_package_offerings.cgi?product=189
This returns information about when a package is available during the year and corresponds with the form below
<row code="141" name="Summer 11:15am extended" product="189" startdate="" enddate="" startmonth="4" endmonth="10" startday="1" endday="11" sun="True" mon="True" tue="True" wed="True" thu="False" fri="True" sat="True" notes="" active="True" lastupdated="6/6/2007 4:14:50 PM" productname="Canyon Connoisseur SBG-5" productcode="189"/>
In order to get availability the following call below is used. If no date param is specfied today's date is used by default
als_get_package_availablity.cgi?product=189
The XML returned includes 3 different name spaces: dates of the Package span, availability and alternate times. Note that a package may span several days.
<dates>
<row startdate="7/2/2007" enddate="7/2/2007"/>
