I scheduled myself from Sacramento, CA to London, and beyond this morning via my VISA miles. I plan to branch off for a week from London to Dublin Nov. 15-22. The agent couldn't find any airfare less than $750 for that period. My understanding is that air travel between the two places is generally low. Perhaps this high cost is caused by business travelers.
In any case, I have a call into Bestfares, where I've seen much lower prices. I'm looking for suggestions here in the event I can't find any low prices. If not, then I may do some other method of transportation. Sea? Spend a lot more time in Britain!
