Morley Selver notes that if you are waiting to board a flight and it is suddenly cancelled, there will be a race to the next airline counter to try to get on the next flight. Instead of following the sheep to the counter, head for the nearest phone and phone the airline reservations system. You get the same result without standing in line. Pets You can ship your pets on an airline, but you need to put the animal in a special animal container. In some breeds with short noses, they can suffer breathing problems and other side effects.
Some countries have really strict pet quarantines.
Special Circumstances There are some things beyond your control, and airlines actually have some flexibility in these circumstances. If you are ill, you can usually cancel or reschedule your flight. You will need a note from your doctor and to fill out a number of forms at an airline office. If you are flying to a funeral of a relative, many airlines will waive the advance purchase restrictions on fares, resulting in much cheaper tickets. You will need to tell the airline the name of your relative, your relationship to the dearly departed, and the name and phone number of the dearly departed's funeral home.
