I read the WSJ article and was happy they did this.

As I have said earlier in this thread, I am not against NDC. But if it’s in any way the same as my own experiences booking direct with AA.com, all I can say is that it is is loaded with frustration when trying to change a booking. Why do I always have to call an AA agent? The AA.com site should be able to handle booking changes. I buy published first class fares, nothing that’s out of the ordinary. But enough of my repeated grumbling on that.

A lot of the success for this NDC model with TMC’s comes down to if it provides a more efficient outcome for travelers and agents. Less friction when it comes to mundane things like changing a booking. From what I have heard it is not as efficient in terms of changing bookings or voiding tickets as the GdS model. But time will tell. TMCs that use NDC do say that changes require manual agent intervention which means having to be appropriately staffed. People cost money so the air savings in NDC may be lost with higher personnel costs.
