I've booked a cruise for the week after Thanksgiving. The cruise goes from Nov 24-Dec 1 out of Miami. I'm planning on flying in on Thanksgiving day (Nov 22) or the day after depending on prices. Right now, flights out of Phoenix are around $450 roundtrip. With the days I'll be traveling, should I book my flight now or wait a little while till prices drop? Any help would be greatly appreciated. Thanks!
