1. Do You Provide Accommodation Services at Transit Locations to Passengers Who Have Connecting Flights?
Passengers have right to have free hotel accomodation only when there is more than 10 hours (7 or more hours for business class passengers) between two international connecting flights due to Turkish Airlines’ schedule structure for maximum 2 nights.
Both of the connections must be with Turkish Airlines, reservations must be confirmed and transfer flight’s reservation must have done for the first scheduled flight. Hotels will be Turkish Airlines’ corporate hotels that will be provided though “Hotel Desk” office which was located at the arrival floor after customs. Passengers should have checked visa procedures in advance. In the event that they are not granted visas at the transit, Turkish Airlines assumes no responsibility for providing hotel services.

1. Not for TK8140 as it is operated by LOT
2. No, because there is a shorter connection available, even though you are not booked on it. TK61 connecting to TK1765 is generally 6,5 hours. Unless you are traveling on days where there are no possible connecting flights to WAW, then the answer would be yes.
