I flew the family to Scotland last year, kept looking at co.com and price was $1000. Orbitz was same, BUT showed KLM at $700. Of course, got full EQM etc. Maybe, the idea now is to make it so that we are penalized for taking a partner's cheaper fares?
Most of these recent changes do nothing to strengthen any of the alliances. Personally, I think CO/KLM/NW should dump Delta and go back to the way things were.
