According to arguments made, the Nicolau award granted WB positions in excess of those held by the USA pilots as a form of accounting for attrition.
Nicolau awarded both the captain and first officer positions on the international 767/757/330 categories because AWA had no pre-merger expectation of those positions. This gave a certain number of AAA pilots who did not hold an international left seat the opportunity to bid it before the number one AWA pilot could.
