Trip Type
How do I specify the trip type (one way, round trip) in the request?
You can specify trip type in the TripType/@Value attribute. For valid values, see the schema. Use the following XML request snippet.
<TravelPreferences> <CabinPref PreferLevel="Preferred" Cabin="Economy"/> <TPA_Extensions> <TripType Value="Return"/> </TPA_Extensions> </TravelPreferences>
