that's just an example for different booking codes, you could use just the one you are looking for or multiple. Hope this helps
Thanks for the suggestion. I tried that already before but the result I'm getting is a series of one-way fares (xxx-yyy and yyy-zzz) instead of booking both sectors on the through fare basis (xxx-zzz) which the rules incidentally allow. So I was looking to see if I could specify which fare code to use but it doesn't seem to work.
