Flight cancellations(取消) and loss of luggage can ruin even the best-planned holiday. The key to a stress-free trip is having a backup plan.

Fly non-stop. The worst problems involve connections, so it is important to take non-stop flights whenever possible. If you do have to make a connection, try to route through a southern city, where snowstorms and de-icing delays will be less likely. Always allow at least two to three hours for flight connections.

Check the weather. Check the weather in your connecting city, not just the arrival and departure city. If your departure flight is cancelled because of weather, you can go home or back to your hotel. Airlines promise to get you on the next available flight, not the next flight. That could be several days later on a sold-out holiday weekend.

Go early. The earlier in the day you fly, the better your chance of getting rebooked the same day after a missed connection. It will also put you ahead of stranded(滞留的) passengers who arrive later.

Rebook immediately. As soon as your flight is delayed or cancelled, get on the phone and rebook your flight instead of waiting at the ticket counter. If your rebooking is delayed, call or ask your travel agent to find a seat on another carrier, and then ask your original carrier to endorse your ticket to the new airline. Airlines are not required to do this but often do. Learn more at www. dot. gov/ airconsumer/ fly-rights.

Ship bags. A few days before your flight, ship suitcases or holiday gifts to your destination by a documented express service. It’s preferable to losing bags because of re-routed flights and sometimes cheaper than paying airline overweight bag fees.

Know your rights. Airlines are not required to compensate passengers for delayed or cancelled flights, but it never hurts to ask for goodwill vouchers(折扣) for meals, taxis or a room.
