How much is a plane ticket from North Carolina to Paris France?

The cost of airline tickets is highly variable on a day-to-day, even an hour-by-hour basis. It will depend on the class of the ticket, the day of week and time of day, and the airline. Many airlines run occasional special discounts, which may be available for very short Windows of time.

If you are very flexible in your travel, it's possible to get very inexpensive tickets if you're willing to go at inconvenient times on unpopular dates. For example, tickets on the day of a major holiday are often a bargain, because most people have traveled before the holiday and plan to return after it.
