There are some implementations that consume WSDL on the client side to 
give you convenient bindings into your language of choice.  There are 
some implementations that consume WSDL on the server side to give you 
convenient bindings into your language of choice.  There are some 
implementations where you build your server side component, and the WSDL 
is automatically generated for the messages it consumes. These are 
implementation level details.  WSDL is not required for web service 
interaction, though it is very convenient.

Your Travel Reservation may choose to use a 'WSDL First' approach, and 
have the WSDL drive how messages are built.  It may not.  The direct 
answer to your question is 'It depends on how it was implemented'.
