With us are a couple we met on the "stand by" list in London to get to Copenhagen. They did their own air. They were coming in a full day ahead. They left their home town and flew to Chicago. The plane sat so long on the ground that by the time they got to Chicago they could not get to Europe that night and had ot stay the night in Chicago. I believe they had a three hour window to make that connection. Should have been plenty of time.
Then the next day when they were supposed to already be in Europe they left for London and ended up in the same boat as us praying for seats to Copenhagen. So this couple did everything possible to make things work.
Believe it or not they STILL DONT have their luggage. We got one bag before we sailed and the next one the next day. It was almost no incovenience at all.
They are a super couple and have the BEST attitude. Between insurance adn the airline allowance they can spend $1500 on clothes but there is almost nothing to buy here. They could have shopped in Trondheim but thought their luggage would arrive.
No matter what plans you make these things can happen. You can limit them with time between connections etc. I do think the key is to make the best of it no matter what.
