Headed to Peru for Xmas this year and starting to look at tickets. Delta's cash fares to Lima in J (they are the only nonstop from LAX), are MUCH higher on the dates we want than what seems to be their "standard" price that far out, likely a function of the holidays; due to the date of our return can't actually book for a few days as those flights aren't open yet and round trip is cheaper. No miles tickets available and very limited date flexibility. Should we expect prices up or down over the next few weeks? Trying to decide whether to suck it up and pay or wait and hope.
