United is one of the first major US airlines to introduce such measures in the wake of the pandemic. The "health self-assessment" is now part of United's check-in process and consists of a questionnaire called the 'Ready-to-Fly' checklist. All criteria must be met before the passenger can continue successfully check in, otherwise they will have to reschedule their flight.
The Ready-to-Fly checklist includes:
- A reminder you must wear a face mask while on board
- A list of common COVID-19 symptoms, and a declaration that you have not experienced them in the last 14 days
- You have not been denied boarding by another airline due to a medical screening in the last 14 days
- You have not had close contact with someone who tested positive for COVID-19 in the last 14 days
The checklist was based on recommendations from the Cleveland Clinic, the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO). It can be done online or at a check-in desk at the airport with a United Airlines agent.
