This is a good explanation in the DL/NW ruling starting on page 26 at the “Constructive Notice” section explaining that the merger announcement date is the seniority list snapshot date:

To summarize, the public announcement date is when pilots are aware there will be a merger with their respective companies. Anyone hired after that date is assumed to be joining the combined company (DOH will be used) as opposed to anyone hired before the Constructive Notice date where there wasn’t any plan of merger.
