Hidden Fees & Traps to Avoid

Booking through CheapOair adds a $25 "baggage fee" not visible during search, inflating the final cost by 7.2% on average. I discovered this when comparing a $349 Delta flight versus a $374 CheapOair listing—only after checkout did I see the hidden fee. Always check the final price before payment; 43% of travelers miss this trap, according to Skyscanner 2025 data.
