Excitedly scoring a 0-dollar budget airline ticket, only to see a checkout of one or two thousand dollars—did you feel scammed at that moment?

Don’t be too quick to call the airline greedy. Not a single cent of this money actually goes into the airline’s pocket, and if you end up not boarding, you can even get a portion of it back.

Why do you still have to pay extra when getting a 0-dollar ticket?

Let’s make one concept clear first:

“0 dollars” means the base fare is zero, not that the entire trip is free.

The total price of a flight ticket is actually made up of three parts.

Total ticket price = Base fare + Airport tax + Additional surcharges

Component	Collected for	Description
Base fare	Airline	The price of the “seat” itself, which budget airlines discount to 0 dollars during promotions
Airport tax and government fees	Government/Airport	Airport service fee, departure tax, security fee, etc. The airline only collects and pays on your behalf
Additional surcharges	Airline	Fuel surcharge, aviation insurance, booking fee, etc.

So, the only truly free part of a 0-dollar ticket is the “base fare”. You still have to pay the remaining airport tax and additional surcharges no matter how cheap the fare is.

What is airport tax? Why are even transit passengers charged?

Airport tax, also known as airport construction fee or departure tax, is a fee paid to the government or airport when flying. It is used to maintain airport facilities, provide security services, and expand runways.

Most countries bundle this fee into the ticket price, collected by the airline, so you don’t usually feel its presence.

All departing passengers must pay an airport service fee, and transit passengers must also pay a transit facility fee.

As long as you use the airport facilities, you must share the cost.

However, there are exceptions. Some airports do not charge transit passengers with short layovers, and infants, children, or diplomats may also be exempt on certain routes. The actual amount varies by departure airport, international versus domestic route.

Confused between landing fees and fuel surcharges?

Airline receipts often list confusing abbreviations. The most common mix-ups are between landing fees and various surcharges. In fact, their charging targets are completely different.

Item	Who pays to whom	Is it related to passengers?
Airport tax	Passengers to government/airport	Directly related, listed on your ticket breakdown
Landing fee	Airline to airport	Indirectly related, runway usage cost for airlines, not charged to you separately
Fuel surcharge	Passengers to airline	Directly related, fluctuates with fuel prices
Booking service fee	Passengers to airline	Directly related, part of the airline’s operating costs

A simple way to tell them apart is to look at the “flow of money”:

Airport tax is paid by you to the airport, while the landing fee is paid by the airline to the airport.

Landing fees fluctuate based on airport traffic, aircraft weight, and takeoff/landing slots. This is part of the airline’s operating costs; while it is eventually reflected in the ticket price, it won’t appear separately on your ticket breakdown.

Did you miss your flight? Is the airport tax gone forever?

This is the part that most people don’t know and where they lose out the most.

Imagine buying a promotional ticket (which might even say “non-refundable/non-changeable”), and then having an emergency that keeps you from going. You likely won’t get the base fare back, but what about the airport tax?

Since the airport tax is “collected and paid on your behalf”, if you didn’t board the plane, this money should be refunded to you.

The airport tax is a “user fee”. If you didn’t use the airport or depart, the government has no reason to keep this money. Therefore, even for “non-refundable” tickets, as long as you didn’t board, you can apply for an airport tax refund.

Application process is actually not complicated:

After confirming you missed the flight, just submit a refund request through the original booking channel.

After confirming the flight was not boarded, contact the airline customer service the next day, or log in to the official website or app.
Submit a refund application for the airport tax of the “unflown segment”.
Monitor the progress; it typically takes 2 to 6 weeks for the refund to be processed.

Before applying for a refund, watch out for these traps

Although airport tax is refundable, there are many details to notice in practice. Otherwise, you might end up empty-handed or find that the refund isn’t even enough to cover the processing fee.

Trap	Description
Refund processing fee	Some budget airlines charge a refund fee. If this fee is higher than the airport tax itself, a refund is not worth it
Application deadline	Budget airlines have strict rules; missing the deadline means forfeiting the refund
Third-party booking	If you didn’t book through the airline’s official website, you must contact the travel agency or booking platform, making the process more convoluted

So before clicking the refund request button, do the math:

If the refund processing fee is higher than the refundable airport tax, it’s better to treat it as a lesson and save your time.

The safest approach is to check the airline’s refund policy and processing fees before buying promotional budget tickets.

Next time you score a 0-dollar flight ticket, don’t be too quick to rejoice or get upset. Open the “fare details” before checking out to see where every cent goes, distinguishing what is for the government and what is for the airline.

If you really end up missing the flight, remember your right to apply for an airport tax refund. Don’t let your own money fly away in silence.
