We usually do our own airfare, but we're flying at Christmas, 12/23 & 1/5 and with weather and crowds we wanted Viking to be working for us if travel got messed up. The flights we got are ones we would have chosen and are $500 cheaper/person than we could get. We're not flying until the end of December and our flights showed up on AA at least two months ago and we've already been able to change our seats. No complaints yet.
