 Delta Airlines profits are down 29%. That's according to the second quarter earnings numbers out to date, and it comes as the U.S. has seen record-breaking travel this year. Melissa Fado of member station WABE has more. The airline points to increased fuel and labor costs and lower base fares across the industry for the downturn. That's despite record-breaking revenue of over $16 billion for the quarter. On an earnings call, CEO Ed Bastian says low-cost carriers are part of the problem, creating an oversupply of seats on domestic routes.
