Avoid Trip
I booked a business flight from Buenos Aires to Paris with Turkish airlines. The flight has a connection through Isantbul. There was a change in the flight from Buenos Aires to which I agreed but the connection in Istanbul was not modified accordingly. Therefore we arrive 12 hours after the connecting flight leaves. I informed Trip.com and they said the can do nothing and that I should cancel the flight loosing 600 dollars in the process. I fell very stupid for using this site, I strongly advise to avoid.
