Through my airline NW I have gotten many ZED tickects for Delta flights, and my experience as a non-rever with Delta has always been great. Mostly JFK-NCE-JFK, and once BDL-LAX (now defunct), always top-notch, and more often than we deserve up front. How will things shake out after the merger? Who knows, but I suppose it will then be easier for me to check loads on DL than it is now.
