No one can say when prices will go down. I can just tell you my last experience buying airfare. We have trip planned to WDW flying from California. When I started looking, 11 months out, the cheapest fare was in the high $400's. But the catch was (for me) the return flight. Sure the departure was in the $400's but on return it just about doubled. I was certain it could only go down, it really didn't. I didn't end up going with that airline anyway (we usually fly United) because of cost and connection(s). We stay away from SFO. Ended up paying more but for better times and staying out of SFO which was worth the extra cost. I've been seeing on the news a lot lately about airlines putting more seats onto planes. We're packed in there as it is. I suggest you buy your airfare when you feel comfortable with the price and not whether it will go down or not.
