It is sometimes difficult to understand the logic behind LH marketing of FRA connection scheduling. Every Friday evening (when delays are particularly common), LH offer LCA-FRA-TXL (LH1293/202) with a connection time of 45 minutes. Since the origin is non-Schengen, going through passport control is necessary and frequently long walks are involved. LH1293 is one of the airline's most unreliable flights, with an average delay of 23 minutes. The EU261 compensation rate must surely be considerable!
