UA policy
Will I have to wear a mask when I travel?
Yes. Federal law requires all travelers to wear a face mask with no vents or openings that fully covers their nose and mouth. Masks must be worn in the airport and during the entire flight, and between bites and sips if travelers are eating or drinking. This includes customer service counters and kiosks, airport lounges, gates and baggage claim areas. A face shield alone does not count as a face covering, and
bandanas are also not permitted. Travelers who aren't wearing their masks in the airport or on board may be refused transport, be subject to fines, and could also lose their travel privileges on future United flights. Children younger than 2 years old are exempt
Bandanas and loose fitting coverings are not considered as as effective as true masks (properly worn)
UA is required to enforce
CDC requirements which state
The following do not fulfill the requirements of the Order.- Masks worn in a way that does not cover both the mouth and nose
- Face shields or goggles (face shields or goggles may be worn to supplement a mask that meets above required attributes)
- Scarves, ski masks, balaclavas, or bandannas
- Shirt or sweater collars (e.g., turtleneck collars) pulled up over the mouth and nose.

- Masks made from materials that are hard to breathe through (such as vinyl, plastic or leather)
