Notice
If the passenger's journey involves an ultimate destination or stop in a country other than the country of departure, the Warsaw Convention or the Montreal Convention may apply to their entire trip, including any portion entirely within the country of origin or destination, and these Conventions may limit the liability of carriers for death or bodily injury, passenger delay and in respect of loss or damage to baggage.  Many air carriers, including United, have waived the Warsaw Convention monetary limits for compensatory damage arising from an accident as defined by the applicable treaty resulting in death or bodily injury.  Further information may be obtained from the carrier. 

Passenger Liability
For those international travels subject to the Warsaw Convention, including special contracts of carriage embodied in applicable tariffs, and/or the Montreal Convention, the UA Carrier agrees that its liability for recoverable compensatory damages for the death of or personal injury to passengers shall not be limited.  However, the UA Carrier reserves all defenses available to such claims.  With respect to third parties, the UA Carrier reserves all rights or recourse against any other person, including without limitation, rights of contribution and indemnity.

Baggage Liability

International
For those international travels, including the domestic portions, subject to the Warsaw Convention, the liability limit for delay, damage or loss is approximately $9.07 per pound ($20.00 per kg) for checked baggage and approximately $400 per passenger for unchecked baggage.  Where the Montreal Convention applies, the liability of the UA Carrier for the delay, damage or loss to checked and unchecked baggage is limited to 1,000 Special Drawing Rights per passenger.

Domestic
For travel wholly between U.S. points, liability for delay, damage or loss to checked baggage, including carry-on baggage if tendered to the carrier's inflight personnel for storage or otherwise delivered into the custody of the carrier, is limited to a maximum of $3,300 per passenger.

For both international and domestic travel, liability for loss, delay or damage to baggage is limited unless a higher value is declared in advance and additional charges are paid.  Excess valuation may be declared on certain types of articles.  Some carriers, including United, assume no liability for fragile, valuable or perishable articles.  Further information may be obtained from the carrier. Additional protection can usually be obtained by purchasing insurance from a private company. Such insurance is not affected by any limitation of the carrier’s liability under the Warsaw Convention or such special contracts of carriage. For further information, please consult your airline or insurance company representative.

Overbooking of Flights
Airline flights may be overbooked, and there is a slight chance that a seat will not be available on a flight for which a person has a confirmed reservation. If the flight is overbooked, no one will be denied a seat until airline personnel first ask for volunteers willing to give up their reservation in exchange for a payment of the airline’s choosing. If there are not enough volunteers the airline will deny boarding to other persons in accordance with its particular boarding priority. With few exceptions, persons denied boarding involuntarily are entitled to compensation. The complete rules for the payment of compensation and each airline’s boarding priorities are available at all airport ticket counters and boarding locations. Some airlines do not apply these consumer protections to travel from some foreign countries, although other consumer protections may be available. Check with your airline or your travel agent.

Additional Terms
