These steps are all from the pov of my application.  I'm assuming that  
there must be messages in both directions. If this were paper based,  
step 4 would include opening the mail and reconciling booking  
confirmations against booking orders sent out in step 2, + separate  
steps to handle timeouts, etc, which I'd expect to be in the context  
of the 'transaction'.  I could write this as a series of async  
processes, but my experience of that type of design when given to  
programmers is that I get much more complexity than I need.

Does that make sense?
