The average round-trip domestic airfare stood at $391 last year, the highest since the federal government started tracking the data in 1995. Despite the higher fare, the demand for air travel is not decreasing, with an increase in the percentage of U.S. travelers planning to fly this year, according to a TripAdvisor survey.

Data from the U.S. Bureau of Transportation Statistics shows the nation’s airline industry enjoyed record profits for the first quarter of this year, due in part to lower fuel costs and high demand. Delta Air Lines reported a first-quarter net income of $746 million, compared with $213 million in 2014, and predicts it will save $2 billion in fuel costs this year. American Airlines reported a record $932 million, compared with $480 million for the same period in 2014, citing a 42 percent decrease in fuel costs.

According to the federal agency, the 2014 average domestic airfare was higher than the average airfare of $389 in 2013. However, when adjusted for inflation, the average airfare is down 16 percent from the high of $467 in 2000.

A new survey from TripAdvisor reveals demand for air travel will continue to remain strong, with 92 percent of the website’s members planning to take a domestic flight this year. The number is up 3 percent from last year, when 89 percent said they flew domestically. Approximately 67 percent of those who plan to travel expect to take an international flight, compared to 60 percent who did so last year.

“This year, we’re seeing more interest in international flights as favorable exchange rates have piqued the interest of U.S. fliers in traveling abroad,” said Bryan Saltzburg, general manager, TripAdvisor Flights.
