Burnham, who has written to security and borders minister Damian Hinds about the support, raised his concerns over the disruption Manchester airport has experienced over the past week.
"Many passengers have faced an unacceptable experience and it is important that every possible step is taken to prevent a repeat," he said.
"People preparing to travel are understandably worried and there is a need for the clearest possible advice before they do. All airports have struggled to one extent or another with lengthy queues caused by staffing issues arising from the pandemic, but it is clear that Manchester has faced particular challenges."
