Airlines are adding health safety measures now that travel is slowly resuming. United Airlines and Alaska Airlines have both said that they will require passengers to fill out a preflight health checklist during check-in. United's policy took effect Tuesday; Alaska's will begin June 30. The checklists vary: Alaska calls it a health and wellness agreement and says travelers must verify they haven't had any COVID-19 symptoms in the past 72 hours or come into contact with someone who is symptomatic. United's "Ready to Fly'' checklist asks passengers to confirm, among other things, that they have not had COVID-19-related symptoms in the past 14 days; been diagnosed with the virus in the past 21 days; or had close contact with someone who has COVID-19 in the past 14 days.
Frontier Airlines, the only U.S. airline taking passengers' temperatures before a flight, asks passengers to complete a health acknowledgment form on its app or website as part of the check-in process. Frontier's questionnaire asks passengers to acknowledge that no one in their household has had symptoms for the past 14 days.
