This is very bad news for us "flyers", i.e. passengers. You can see where the fares go, if you consider routes where there's no competition between LH and AB. E.g. ZRH-FRA this Friday same day return CHF 910 (LH group only, no competition), ZRH-TXL or ZRH-DUS both CHF 210 (competition between LH group and AB)
