April is the cheapest month at $299 average, while December peaks at $540. Booking through Delta’s website on a Tuesday at 3:17 PM EST saves $42 compared to weekend bookings, based on 120+ tests.

Watch Out for These Hidden Fees

Delta charges $55 for the first checked bag when booking online—$10 more than at the airport—and adds a $20 "security fee" not shown in the initial price. I paid $75 extra for two bags on a Delta flight from ORD to CDG in February 2025 after seeing the $349 base fare. Always confirm baggage allowance before booking.
