For those concerned with the cost of one-way fares: I have found that round-trip fares are often the same, sometimes even LOWER, than one-way fares. Since I love repositioning cruises I always pick a possible future "going the other way" cruise and schedule my return flight to coincide with it. If I later get a good price on that cruise, great! If not, I could just throw away my return ticket. That's never happened yet, although I did once pay a change fee to pick up a different cruise than the one I had originally thought about.
