Q. I've enrolled in several different frequent flier programs over the years and somehow have never managed to save what it takes for a trip to Europe. Is there a frequent flier program that allows my wife and I to combine our earned miles into one account?

A. As it stands, there aren't any
domestic carriers that offer such a program. However, since you're interested in travel to Europe, you may want to check out the
British Airways Executive Club, which allows a Household Account, good for up to 4 family members.  You might also consider the
Family Club  from Japan Airlines, which is similar.
