Final answer:

Step-by-step explanation:
During the boarding process, the responsibility for contacting Medlink for passenger fitness-to-fly assessments falls on the airline staff, specifically the ground operations or customer service team.
When a passenger requires a fitness-to-fly assessment due to a medical condition or recent illness, the airline staff will liaise with Medlink, which is a specialized medical advisory service.
Medlink will review the passenger's medical information and provide guidance to the airline on whether the passenger is fit to fly or requires any special accommodations or medical assistance.
