Some budget airlines offer tempting low ticket prices but make up for it with high fees for baggage, seat selection and even onboard refreshments. The total cost can sometimes surpass that of a full-service airline — with way more hassle.

Here are three airlines to avoid when traveling on a budget:

• Spirit Airlines: Notorious for leading the way in separate pay for all luggage, Spirit also gets poor reviews for delays, cancellations and extra fees.

• Frontier Airlines: You can find extremely cheap flights, but keep in mind the extra costs for carry-on bags, checked baggage, seat selection and more. This airline based out of Denver also has a reputation for disrupted and delayed flights which may be worth more than you don’t pay for.

• Sun Country Airlines: Based in Minneapolis, this small airline operates throughout the U.S., Central America, Canada and the Caribbean, but many flights have to be routed through Minneapolis. Customers also have to pay for carry-ons, checked bags, advance seat selection and all snacks.

Outside of specific airlines to avoid, there are also airports you should fly over altogether. Certain airports, such as LaGuardia Airport (LGA) in New York, are notorious for frequent delays and cancellations. Travelers might prefer to use alternative nearby airports to avoid potential travel disruptions.
