Earlier on I mentioned the new Air NZ concept as an example. I'm not sure if everyone is familiar with it so here is a link: http://www.airnewzealand.co.nz/the-choice-is-all-yours

I think it is also quite readable. I know some have mentioned that the differences could be made clear on the af website but not on TA websites, but remember the big rule of European LCCs is to focus on own sale channels as much as possible (so the cheapest U2 fares are not available on expedia etc even though other more expensive ones are). NZ does the same - if you buy on TA websites you only get "seat+bag" or higher. If you want the cheapest "seat only" it's on the Air NZ website or nothing...
