I am sure this has been asked often but I can't seem to come up with the right search terms.

I am looking at RDU-DTW-PVG-HKG-DTW-RDU on DL/CX in early June for 12 days. The fare is currently pricing at $1600 even. The last time I went to China (June 2007) we flew SEA-NRT-BKK-HKT-KUL-PEK-NRT-SEA on NW/MH and it was $1800ish so $1600 seemed reasonable.

Am I going to see much change in the price between now and June or should I just book now. I guess the worst case booking now is losing $250 on the change fee and getting a credit if it does drop.

Any thoughts?
