If you wish to send a complaint via post to the airline, the mailing address is:
Customer Relations
WHQPW
United Airlines
PO Box 66100
Chicago, IL 60666
but odds are it will end up in the same basket as all the others, regardless of whose name you put in the envelope.
Telephone and Fax numbers for Customer Relations are:
* A reader notes: The (847) 700-6796 number just plays a recording
telling you "in the name of better service" to call the other
(toll-free) number. That number connects you to someone who speaks
about 500 words of English and uses them to tell you how sorry they
are that you got screwed and that someone will be contacting you in a
few days.
UAL no longer advertises a general email address for the submission of
complaints, but instead, directs passengers to this
on-line
form with a tiny text box for entering your message. Given the
limited attention span of UAL's customer relations department
employees, the size of that text box may be informative.
Telephone: (877) 228-1327 (toll-free) or (847) 700-6796*
Fax: (877) 406-1059 (toll-free) or (847) 700-2214
