Is the JR pass worth the expense?

We're planning a 14 day visit. Roughly half of it in Tokyo and half in Kyoto.

We still have to decide on the flight. We might land in Tokyo and leave from Osaka, so that would make the JR pass not worth it, but should we decide to land and leave from the same airport (or city anyway) we would have to get a return ticket for the shinkansen. Would it be worth it then, considering we will be using public transport in both cities?

I know not all public transport is JR, I'm not sure how to evaluate how much of the JR public transport we'd be using and whether that would make the JR pass worth its price.

Refund office address for Turkish Airlines?

My flight to Istanbul from Lviv was delayed for over 5 hours. Because of that I missed my flight from Istanbul to US. I had to wait at the airport for over 20 hours for the next flight. Airline didn't offer me anything in return (hotel, indirect flights, transportation, food). They told me that they are unable to offer me anything in Istanbul because I was a US citizen. I recently had an operation. So, staying and sleeping on the floor at the airport was not the easiest thing for me. Which office do I contact to get at least a partial compensation? Could you please help me locate Turkish Airlines compensation office address.

If you're flying KLM, are you also flying Air France?

If you're flying KLM, are you also flying Air France? - 1

Added (1). It sounds like an odd question, but the reason why I'm asking this question, it is because Air France KLM is now one company, even if KLM is Dutch and Air France is French.
