I am planning to go back from BKK >> LAX soon. Do all airlines (JAL, ANA, KOREAN, ASIANA) require passengers to wear mask the whole time during in-flight and how full is the flight?
Thank you
TLDR : Answer Summary
All mentioned airlines (JAL, ANA, Korean, Asiana) require passengers to wear masks throughout the flight, except when eating or drinking. This is a common policy among airlines globally during the pandemic.
