This comes especially handy when you try to build an RTW or try to find some less expensive itinaries like Asia - Europe (stop on one or both directions) - America.
But be warned: lots of reading really boring text. BKK-NYC for example has 16 different fares for First. And each fare has many pages of rules.
Yes but not much use when LX & LH don’t follow the rules they publish….
