This question already has an answer here:
(Couldn't find an appropriate topic that answers my question. I understand why round-trip tickets are cheaper and why non-direct flights may be cheaper as well, but this is just ridiculous)
I was planning a trip to Germany with Lufthansa the next week and was searching for tickets between LED and TXL. I found out that it will cost 21k RUB and there is a transfer in FRA. As you can see, a trip consists of LH1439+LH176 and LH193+LH1438.
Okay, so I guess I could just have a nice trip to FRA and save myself money and time? Like just use LH1439 and LH1438. Nope, it actually costs 70% more.
How is that even possible?
