Before your trip

• Avoid booking flights with partnering airlines. If possible, try to travel with one airline carrier for the entire flight, including any connections. This helps avoid reticketing issues, should one leg of your flight get canceled.

• Confirm your flight. Up to a week in advance, contact the airline to confirm your itinerary and other details, or visit the airline website. Seating assignments sometimes change without notice, especially for long-distance flights on large aircraft.

• Pack wisely. In a carry-on bag, bring medicines, extra diapers, your cellphone charger, and iPad or tablet charger, a change of clothes for each family member, and any items that will help soothe young children during an unexpected overnight stay, such as a favorite toy or small blanket.
