Delta Air Lines is increasing the fee to check bags, matching moves by some other carriers.
Delta now charges $30 for a first checked bag and $40 for a second checked bag.
That’s up $5 from the previous fees of $25 for a first checked bag and $35 for a second checked bag.
United Airlines and JetBlue Airways have put in place similar baggage fee increases. By midday, American Airlines had not increased bag fees.
Southwest Airlines lets passengers check up to two bags free.
Airlines have been pulling in more revenue from extra charges for several years. Last year, U.S. carriers raised $7.4 billion from fees on checked bags and ticket changes, led by American, Delta and United.
