Turkish Airlines/Lufthansa changes in flight schedule
 

I am have a situation involving Turkish Airlines and code share partner Lufthansa. Last March Turkish Air offered a super good promotional fare from LAX to Nairobi vis Istanbul. I booked two tickets for travel on Nov. 2, 2011. LH has advanced their LAX-FRA departure time resulting in 30 minutes connect time Istanbul which is obviously impossible to make. After checking with LH, I learned there was actually two itinerary changes, which according to LH were made on 6/16/11. Turkish was kind enough to only notify me of only one change which affects my connecting flight on my return leg. I was told nothing about the outbound LAX-FRA flight schedule change.

There solution being offered by TK is to depart a day earlier and stay overnight at my expense, or get a full refund. With fares running about $1,400 I'm inclined to bite the bullet and pay for a hotel stay in FRA. Is there any other recourse or rights I should be entitled to for this involuntary schedule change? Thanks for listening.
