From the article:
‘Amsterdam is of course a huge hub for SkyTeam member KLM, which dominates the airport. Meanwhile Star Alliance operates its own lounge at the airport, and now oneworld plans to operate its own lounge there as well.’
KLM has a huge non-Schengen lounge for SkyTeam members.
So it would make sense if the old BA and Aspire lounges merged to create a new oneworld lounge IMHO.
