      abstract     = {We benchmark the quantum processing units of the largest
                      quantum annealers to date, the 5000+ qubit quantum annealer
                      Advantage and its 2000+ qubit predecessor D-Wave 2000Q,
                      using tail assignment and exact cover problems from aircraft
                      scheduling scenarios. The benchmark set contains small,
                      intermediate, and large problems with both sparsely
                      connected and almost fully connected instances. We find that
                      Advantage outperforms D-Wave 2000Q for almost all problems,
                      with a notable increase in success rate and problem size. In
                      particular, Advantage is also able to solve the largest
                      problems with 120 logical qubits that D-Wave 2000Q cannot
                      solve anymore. Furthermore, problems that can still be
                      solved by D-Wave 2000Q are solved faster by Advantage. We
                      find, however, that D-Wave 2000Q can achieve better success
                      rates for sparsely connected problems that do not require
                      the many new couplers present on Advantage, so improving the
                      connectivity of a quantum annealer does not per se improve
                      its performance.},
