The other day I happened to be booked on Turkish Airlines flight TK 1808 from LYS to Istanbul, with a connection to the far east.
It appears that TA cancelled the flight.
It's true there was some rain in Istanbul.
However, a number of people have asserted that TK rather often "economically cancels" flights. So, if there are only a few people on a flight and they have another shuttle later, they cancel one "because of weather" or for "technical reasons."
This could be a completely untrue rumour, but going back 20 years in the US, industry people would say this happened, i.e. with frequent shuttle routes and the like.
Note that the online history link above only shows a couple weeks so I can't really judge.
is this evil rumour about TK true?
in general (I'm thinking more here in Europe) is this sort of thing common? Or perhaps in other regions?
is there any other good way to check if a flight you are thinking of using to link to a hub, "tends to get cancelled"?
