My wife and I decided on a Med cruise out of BCN next June. Started checking and calling late July... all the city pairs that were suggested by Vinnman (was a great help), then around four weeks ago Ind to DUS became available on several dates in June. I booked (held) the dates in B/E at 90K each and called Delta about connecting to BCN with AF (also all Bus.). My routing is: Ind-ATL-DUS-CDG-BCN with return BCN-CDG-DUS-ATL-IND.
On the return we took a 27 hour stopover in Paris as my wife wants to see the Louvre. We get to DUS at 4:50 PM , ( plan to spend the evening in the Altstadt) leaving on Delta 25 the next morning at 9:40 (not a stopover since that was the first available TATL connection). Not the best connection, but I was determined to use my miles as it continues to get more difficult getting Skysaver award seats.
