Similar experience on the other side of the pond, tying to get "nice" itineraries to the US. During the pre-merger times, the flight selection never included the only nonstop flight on DL metal from STR to ATL - only routings via CDG, nor did you get any AMS connections. Since the merger all the sudden, they only prompt me ATL connections with insane layover times and even overnight stops - this is for flights to DTW, ORD or the eastcoast (!!). Who will buy a 16+ hr ticket, for what can be done in 11. Pricing on these itineraries is through the roof as well. Where are all the flights via AMS gone that, during NW times, were easily available? I mean, they signed a codeshare aggreement last year...
Also very frustrated with the ability to check/edit your itinerary online when being booked on KLM, but flying DL metal - no chance to select seats, goofy formated itinerary prints....
Wishing back nwa.com - you should expect, if two companies merge, the better system will succeed
