Just give it some time
Come on people.
The complete transition is a whole weekend project, perhaps longer. Some data may be transferred automatically and others will require a manual input. (such as interline agreement information, etc?). It is also not very difficult to imagine, that the staff-travel part of the transition project will take a back-seat to the customer front end...
We all are complaining about the shortsightedness and ignorance of non-aviators, but the above posts are just another point in case, that we are not any different.
This "it's all about me" attitude is really not helping anyone. Sad.
