Hi, we have been traveling to WDW for Easter week for many years now and I always pay from $59.00 - $89.00. I start checking as soon as vacation is approved at work for airfare and note that the rates change sometimes throughout the day. I've checked in the AM and get one rate and another rate in the PM. We sometimes leave on one airline and return on a different one or different airports. My advice is check and check and check and buy as soon as you get what you know is the cheapest rate your going to get.
Good luck, hope this helps
