Options for Travelers Considering Trips to Paris

— -- Though the U.S. State Department had issued no travel alert or warning for Paris as of this morning, the question on the mind of travelers with booked trips to Paris remains: Should I go?

The coordinated attacks throughout Paris on Friday that left nearly 130 people dead have no doubt scared potential visitors away and it will be some time before the cost to the city is known. But for people already holding airline and hotel reservations, there are options.

Several airlines have issued fee waivers for customers who wish to postpone trips. On American Airlines, customers who purchased tickets to Charles De Gaulle Airport prior to Nov. 14 and are scheduled to travel before Nov. 22 may change their trips to travel before Dec. 15. United, Air France and Delta have issued similar policies.

Hotels generally have far more flexible cancellation policies than airlines, with many allowing cancellations up to 24 hours before scheduled arrival date with no penalty. This may differ for travelers who booked hotels through third-party sites and chose a discounted rate that did not allow cancellations. Expedia declined to comment on hotel bookings and cancellations in Paris in the wake of the attacks.

Typically, third-party travel sites are bound by the rules put forth by the supplier. So, a flight booked through a site like Expedia would be bound by the same cancellation or change policies as the hotel or airline in question.

Starwood Hotels in Paris are waiving cancellation fees for arrivals through Friday, Nov. 20. Airbnb is working with hosts in Paris to accommodate travelers already in the city for free.

Though travel insurance policies vary widely, many do cover acts of terrorism as long as the insurance was purchased before the incident. A spokesperson for Squaremouth, a travel insurance provider, however, told ABC News that policies there may be additional requirements.

"Some policies require that the city -- in this case Paris -- be on the traveler's itinerary, or that a city within a specified distance, often 50-100 miles, is on their itinerary," the spokesperson said. "Many policies require the traveler's departure date be within the next 7-30 days following the attack, so those with travel dates after mid-December, or even later this week, may not be covered depending on their policy details."

Allianz Global Assistance, which is based in Paris, said policies do provide coverage for trip cancellation and trip interruption when there is a terrorist event at the customer's destination within 30 days of the day they are scheduled to arrive. Allianz Travel Insurance customers who are already in Paris and wish to return early may receive payment for their unused prepaid expenses and may be covered for additional transportation costs to get home early.

Those who proceed with previously-planned trips should expect additional a heightened security presence around the city and at popular attractions. The Eiffel Tower remained closed Monday, but several museums, such as the Louvre and Musee d'Orsay, have reopened as of Monday afternoon.
