In the case of death, you'll probably need to provide the name and phone number of the funeral home. If you lose your airline ticket, you must fill out a lost-ticket application. In addition, you usually have to pay some sort of service charge or penalty for a replacement ticket. After a waiting period of three months to a year, the airline will issue you a refund for the price of your replacement ticket if your lost ticket was not used during that time. The policies on lost tickets vary among airlines.
Policies are generally looser on international flights.
For example, if on the first leg of a round trip between Boston and New York, the agent takes your New York to Boston coupon by mistake, you will be left in New York with a seemingly worthless Boston to New York ticket. You can avoid this predicament by double-checking your remaining ticket coupon as soon as you enter the aircraft. The return trip was booked London to New York and New York to San Francisco. The student stated that when she arrived in New York, she discovered both the London to New York coupon and the New York to San Francisco coupon had been removed from her ticket so that she had no way to return to San Francisco. Her conclusion was that the gate agent had mistakenly taken both coupons from her ticket when she left London.
