Watch Out For: Hidden Fees & Traps

Spirit Airlines lists $89 base fares but adds $25 for carry-ons at check-in—confirmed when I traveled March 2025. Booking.com hides a 14.5% "convenience fee" on top of $329 fares, making the true cost $378. Always check the final price before paying. I paid $15 extra for a 15kg bag on United (UA) when the site showed $219.
