Why 'Cheap' Flights Deserve Skepticism Before You Click Confirm
A fare that looks like a deal at first glance can unravel fast. Baggage fees, visa costs, mandatory travel insurance, airport transfer expenses, and currency conversion charges can stack up quickly — sometimes exceeding the cost of a standard fare on a full-service carrier. As we explore in our breakdown of what 'cheap destination' really means, low headline prices rarely reflect the full picture.

Run through each item systematically and you'll have a much clearer sense of the real cost — and whether the booking makes sense for your situation.

These rules can change with little public notice. Always verify directly with the destination country's official embassy or consulate website, and cross-reference with the US Department of State's country-specific pages.
