We passed the weight test!! I managed to get everything except my formal stuff into one larger suitcase and it only weighed 55 pounds. Gee--I could bring 15 more pounds of stuff, but I'm not going to, I probably have too much stuff already. DH will also have one larger suitcase and all the formal stuff and his sport coats, etc. will go in a garment bag.
Maria, if we were going back through New York, we could check a bag for you since we only have three--but we're going through Boston. How big are your bags? If you use some bigger bags for this trip, would that help? DH1 could take back the two big bags, plus a carry on. You could check 44 pounds of stuff in one smaller 22", expandable bag, and put the rest of your stuff in a 22" rollaboard as a carry on. One other thought--are you taking Iberia out of Copenhagen? Isn't that considered an international flight? If it is, the weight limits are higher. Maybe not, though, since Denmark and Spain are both EU. You will have a higher weight limit on your flight home, though--is that on Iberia also?
