Delta Air Lines will increase checked bag fees by $10 for first two bags and $50 for third on domestic routes.
The fee hike is Delta's first domestic baggage increase in two years, following similar moves by United Airlines and JetBlue.
New fees become $45, $55 and $200 for first, second and third bags, helping offset jet fuel costs from Middle East tensions.
Stocks fell: Delta -1.72%, United -2.91%, JetBlue -2.95% after the announcement.
