Airlines are increasing their opposition to the consumer protection rules the Department of Transportation announced in April, with two carriers (Spirit Airlines and Allegiant Air) filing separate suits in a U.S. Appeals Court in Washington, D.C.Allegiant has asked the court to review the plan to change the way airline fares and baggage fees are disclosed and to let consumers get a refund within 24 hours of buying an airline ticket as well as a ban on raising airline prices after consumers buy their ticket. Spirit’s suit also challenges the regulations on refunds and full-fare advertising.Source: Travel Pulse; find article here>>.
