Maybe you could add a 'worst airlines' poll and send em that - might help em look at where they're failing ? Presuming they give a ****.
By far the worst I've seen is Air Canada, where pax are purely an annoyance, obstructing their plan to make as much money as possible. I don't think I know anyone with anything good to say about them, who hasn't had a bag go missing or a totally apathetic staff member mess them about. At least you almost expect it with the budget crowd !
I'm told Lufthansa cut the mustard with pax care on long haul, but don't have personal experience.
