Thank you for your wonderful contribution. I have never seen such a powerful search engine before and I love using it for all my Star Alliance flight searches and it includes Etihad as an added bonus. It is also very flexible with separate tabs for duration, aircraft etc.,
My only suggestion for future changes would be to tweak the "mixed cabin" tab, which is showing 100% even for the connections with available business class on both legs.
I am thinking it should show "0%" if it is not a mixed cabin (Air Canada site leaves it blank) but I could be wrong.
Etihad Example
Great work again!
