Delta Air Lines‘ revenue from baggage fees last year averaged out to about $8.58 per passenger, the second highest rate in the airline industry. Atlanta-based Delta has increased its baggage fees over time and currently charges $25 for the first checked bag and $35 for the second checked bag on domestic flights.
Among major carriers, only US Airways brought in baggage fee revenue at a higher rate at $9.91 per passenger.
Southwest Airlines brought in an average of just 28 cents in baggage fee revenue per passenger. Dallas-based Southwest does not charge fees for the first two checked bags but does charge for additional bags beyond two.
