Hidden fees to avoid: Delta's bag trap
Delta’s website lists $198 for basic economy but adds $30 for the first checked bag at checkout—totaling $228. I discovered this when I booked a $198 DL348 flight in March 2025 and paid $228 at the airport. United’s $35 bag fee is upfront, while American includes one bag in the base fare. Always check the "baggage" section before booking.
