"We appreciate that the House Transportation and Infrastructure Committee is working to improve the traveler experience, and we hope its members will make the necessary changes to ensure travelers have the most accurate and complete information possible."

H.R. 4156 purports to boost transparency by allowing increased disclosure of the taxes and fees built into ticket prices. But the bill would permit advertisers and other sellers of air transportation to hide the bottom-line cost of airfare in separate links or in pop-up windows, making it more difficult for consumers to quickly understand and easily compare "all-in" prices among carriers. Dow argued Congress should make sure consumers have both. "Don't just swap one kind of transparency for another," he said. "Let's take this opportunity to shine a full light on the costs associated with air travel."

Dow noted that much of the extra cost of travel funds essential services, such as security and facilities upgrades, that directly benefit the traveler. He argued it's only logical to let travelers know all of what they're paying for. Dow also pointed out that other industry sectors for example, car rental vendors routinely build taxes and fees into their advertised costs.
