From the Federal Cartel Office's point of view, Deutsche Bahn AG has discriminated against mobility platforms. The authority is of the opinion that advertising bans, vertical price specifications, discount bans and the refusal of commissions are anti-competitive. DB AG is suing against the competition watchdog's final decision. Ryanair and Deutsche Bahn are very similar in at least one respect. Both companies are against third-party providers selling their tickets. Apparently they would prefer it if only they and no one else handled the sales. Deutsche Bahn tolerates third-party providers who are active via apps, for example, but imposes strict conditions. These are precisely the conditions that the Federal Cartel Office has now declared to be anti-competitive. The authority also classifies the fact that it does not want to grant other platforms access to real-time traffic data as an abuse of the market-dominant position. The railway operator's app is also particularly in its sights. The Federal Cartel Office is of the opinion that it is anti-competitive for Deutsche Bahn to impose an advertising ban on third-party providers, to set prices and also to prohibit its own discount campaigns or customer loyalty programs. This does not apply to special DB campaigns that are specifically designed to improve the utilization of individual trains. Deutsche Bahn must also pay commissions that at least cover payment and booking costs. However, Deutsche Bahn has no intention of working with third-party providers in the way that the Federal Cartel Office is demanding. It has announced that it will appeal against the authority's decision, as the state-owned company is particularly annoyed by the fact that online platforms should be paid commissions for the sale of tickets. It points out that it itself has an extensive sales network.
