The funny thing, to me, is the range in prices for the same basic service, we're flying out through MSP and back direct, to fly direct both ways would cost over half again as much. Some other one stop options were also much more, and selecting the correct days had a similar savings.
The tickets were $2880 each for "premium" on Delta/KLM. Some options were over $5 K each if you pick a day or three later or earlier.
Now to get a hotel. This is a ten day journey.
