Dear all, perhaps the experience of some of you can tell, what is going to happen in the following situation.

In several weeks, I am going to fly (in Economy) from TLL to IST, continuing to SFO in the next day. At the day I'm flying, there are two flights from TLL to IST by TK. The first of them arrives at 17:XX (I guess there is no point in looking up the exact minutes), which is 20 hours and XX minutes before the flight to SFO departs. The second of them arrives at 23:XX, which is 14 hours and XX minutes before the flight to SFO. The later flight from TLL to IST is also the shortest transit from TLL to SFO.

I'm booked on the earlier flight from TLL to SFO, which makes me eligible for the stopover hotel. I have gotten the voucher. TK has now changed the time of that flight. Well... it's not much of a change, considering that the arrival time of the flight has not changed. Still, I am now eligible to freely change my flight. Also, some personal matters may make me prefer the later flight from TLL to IST.

Question: what happens with the hotel voucher, should I go and make the change? Will it stay valid, or will it be voided? If it will be voided, will I be notified of it before I reach the hotel?

I presume that if I were to change the flight, I will still be eligible for the transit hotel. Should I perhaps go and make the change? My voucher is for Grand Yavuz.

Thank you for your input.
