1.Handy advice you should be aware of
Avoid walking barefoot. Cabin floors can harbor unseen spills and residue.
Lavatories may not be spotless so after washing use a tissue or wipe to limit contact. Disinfecting wipes also help clean tray tables which might not be fully sanitized and may have been used for varied tasks.
Wipe the tray before placing food on it. This simple step reduces exposure to unwanted germs.
