I got $1850 in Business class on Skyteam from DFW to BCN RT for June end to July 4th weekend X 2 adults. (The ticket from DFW to MAD was $150 more in Business class if booked via KLM website yesterday).
Checked the fare an hour later and it was $4500 a person. At the time I booked the deal the Business class ticket was $120 more than the Eco ticket offered by Skyteam to BCN from DFW (same flights).
Checked this morning OW (One World) is selling it for $2750 RT.
