In Seattle admission to the terminal was supposed to be by the arrival time on your boarding pass, but that wasn’t adhered to. Once inside the building and through security, there were separate check-in lines for suites, diamond/platinum, and general. But once boarding started, it was strictly by the boarding group number on your boarding pass. Suites were called first, then A01, A02, etc. People in wheelchairs went right after suites, at the same time as A01.
