If you fear that your flight may be affected, keep an eye on the weather and your airline's Web site for advisories, and make sure your airline can reach you.
"When customers are making their reservations, they should do everything they can to ensure that we have either the best phone number or the best e-mail address for them, because that enables us to send them updates on their flight status," Delta Air Lines spokeswoman Susan Elliott said.
Airline passengers usually have little recourse if their flights are delayed or canceled due to weather, but major named storms are an exception.
