UNITED AIRLINE’S BAGGAGE LIABILITY INFORMATION FROM THEIR WEBSITE:
http://www.united.com/WEB/en-US/Content/travel/baggage/liability.aspx
.
.
The United States Department of Transportation (DOT) requires airlines to reimburse passengers up to $3,400.00 for lost, damaged or delayed baggage to cover all reasonable, actual and verifiable expenses you incurred due to the delayed bag.  And the airlines CAN’T put limits or requirements on expenses.

IMPORTANT:  If you are away from home dealing with a delayed bag you are allowed to purchase essentials to help get you by until they find your bag.  If you do purchase something keep all receipts as you’ll need them to get reimbursed (the airline will require a receipt and won’t take a credit card statement).

While it’s NOT a requirement, if you can contact United Airline’s baggage resolution team at:
https://www.united.com/web/en-US/content/Contact/baggage/default.aspx ) 
Or 281-821-3526 (local) or 800-335-2247 (for authorized purchases) and get prior approval before purchasing any needed essentials then that may help speed up the reimbursement process.

You may want to file a formal complaint with United and if you do then please make sure you do it through Customer Care and using this form:

https://www.united.com/web/en-US/content/Contact/customer/default.aspx

Please note that the minimum response time to hear back from the Customer Care team is 3-5 weeks (depending on status) so don't expect an immediate response.  Make sure if you do file a report with the CC team that you get a CASE ID NUMBER as the CC team should send an automated response confirming receipt of your report.  Within this receipt there is a Case ID number and without it United will tell you to please submit your request again.

If you submitted a complaint and “didn't” get the automated response with a Case ID number then check your SPAM folder to see if it was diverted there instead of your In-Box.
.
.
You should also make sure to file a complaint with the U.S. Department of Transportation's (DOT) Aviation Consumer Protection and Enforcement agency and this is why:

All complaints are entered in DOT's computerized aviation industry monitoring system, and are charged to the company in question in the monthly Air Travel Consumer Report.  This report is distributed to the industry and made available to the news media and the general public so that consumers and air travel companies can compare the complaint records of individual airlines and tour operators.  These complaints are reviewed to determine the extent to which carriers are in compliance with federal aviation consumer protection regulations.  This system also serves as a basis for rulemaking, legislation and research.  Where appropriate, letters and web form submissions will be forwarded to an official at the airline for further consideration.

Complaints are broken down into 3 categories: Safety and Security Complaints / Airline Service Complaints and Comments / Disability and Discrimination Complaints and you can reach all 3 at this link:

https://www.transportation.gov/airconsumer/file-consumer-complaint

You have 3 options when it comes to submitting a complaint: you can call, write or use their web form.

You should know that very little goes from Facebook/Twitter (the Social Media Team) to the executives who really need to know about these problems and issues.  If you wish to contact United’s headquarters to let them know you’re not happy with the service you received then you can find plenty of UA HQ contact info (email, phone & address) for people and departments on my UA Tips & Secrets web page @ http://www.uatipsandsecrets.com/Tips---Secrets.html

Good Luck!
