Key Takeaways
- Budget airline base fares typically exclude baggage, seat selection, and in-flight refreshments.
- Carry-on bag fees vary widely — some low-cost carriers charge for overhead bin space.
- Paying by credit card or booking by phone can trigger additional processing fees.
- Strategic packing and advance fee review can keep the final price genuinely competitive.
- Not all budget carrier fees are unavoidable — knowing which ones to sidestep matters most.
Genuinely lower base fares on many routes
When a route has low-cost carrier competition, base fares are often meaningfully cheaper than full-service alternatives, even after accounting for some add-ons.
Personal item allowance typically free
Most budget carriers allow a small bag that fits under the seat ahead at no extra cost, which covers many short-trip travelers entirely.
Non-alcoholic drinks often included
Water and basic soft drinks are usually provided without charge on most budget carrier flights, even when meals are not.
No-frills boarding is usually efficient
Without assigned seats or tiered boarding classes, some budget carriers move passengers on and off planes faster, which can mean more on-time departures.
Baggage fees can erase fare savings quickly
A round-trip checked bag fee can add $60–$140 or more to a booking, sometimes exceeding the price difference between the budget fare and a full-service ticket.
Seat assignment often costs extra
Travelers flying with family or companions who don't pay for seat selection risk being split across the cabin, particularly on fuller flights.
Limited flexibility on changes and refunds
Many budget carriers offer no-refund or credit-only policies, and change fees can be high relative to the original fare paid.
Secondary airports add transit time and cost
Low-cost carriers frequently use airports further from city centers, meaning ground transport costs and time should be factored into the real comparison.
Last-minute fee additions catch many travelers off guard
Fees added late in the booking process — for payment method, seat, or priority boarding — can feel like a bait-and-switch if you're not expecting them. Overpaying at the airport often starts well before you arrive.
Our Verdict
Budget airlines can deliver real savings, but only when you understand exactly what the base fare does and doesn't include. The travelers who come out ahead are those who do the fee math before booking, not after. When the add-ons fit your travel style — or can be avoided entirely — a low-cost carrier often beats a full-service ticket on price.
Ideal for light packers flying short-to-medium routes who are willing to review fee schedules and make deliberate choices about which extras they genuinely need.
The Base Fare: What You're Actually Buying
A budget airline's advertised price typically covers one thing: a seat on the plane, usually in a fixed middle-of-the-cabin row with no guarantee of where. That's it. The fare gets you from point A to point B — everything layered on top is optional, priced separately, and easy to miss if you're clicking quickly through a booking flow.
Understanding this upfront reframes how you should shop. Rather than comparing headline fares directly, understanding what moves the total price means building out your realistic all-in cost before assuming a low-cost carrier is the cheaper option. Sometimes it is. Sometimes a full-service ticket with a bag included comes out ahead.

US airline ancillary fee revenue (2023)
According to the US Department of Transportation, US carriers collectively collected tens of billions in baggage and reservation fees in recent years, reflecting how central add-on charges have become to airline economics.
40–60%
Share of low-cost carrier revenue from ancillary fees
Industry analysts have estimated that ancillary revenue — fees beyond the base fare — accounts for a significant portion of total revenue at many low-cost carriers globally.
What Budget Airlines Almost Always Charge For
These fees are the ones most likely to inflate your final bill:
- Checked baggage: Almost universally an add-on, typically ranging from around $30 to $70 each way depending on the carrier and when you pay. Fees added at the airport gate are often the steepest.
- Carry-on bags: Some low-cost carriers now charge for bags placed in the overhead bin. A personal item that fits under the seat in front of you is usually still free — but check the size limits carefully, as they vary.
- Seat selection: Choosing your seat — window, aisle, exit row, or front of cabin — typically costs extra. Declining to pay means the airline assigns you a seat at check-in, which may separate you from travel companions.
- Printing your boarding pass: Some carriers charge a fee if you need a paper boarding pass printed at the airport rather than using a mobile boarding pass.
- Flight changes and cancellations: Low-cost carriers generally offer limited flexibility. Changes often incur flat fees plus any fare difference, and refund policies can be highly restrictive.
These charges are part of a broader pattern of fees that inflate travel costs across the industry — not unique to airlines.
Fee Schedules Change Frequently
Budget carrier fee structures are updated regularly, sometimes seasonally or in response to fuel costs and competition. Always verify the current fee schedule directly on the airline's official website before completing your booking. Third-party comparison tools may not reflect the most recent changes. This is especially important for baggage allowance dimensions and weight limits, which vary by carrier and route.
What They Usually Don't Charge For
Budget airlines aren't all fees, all the time. Most include:
Genuinely lower base fares on many routes
When a route has low-cost carrier competition, base fares are often meaningfully cheaper than full-service alternatives, even after accounting for some add-ons.

Without assigned seats or tiered boarding classes, some budget carriers move passengers on and off planes faster, which can mean more on-time departures.
Knowing what's included by default helps you avoid paying for things you'd already be getting for free.

How to Minimize the Fee Impact
The travelers who get the most value from low-cost carriers tend to follow a consistent approach. First, they check the carrier's fee schedule — not third-party summaries — before booking. Fee structures change, and the official site is the authoritative source. Second, they pack to the personal item limit, avoiding checked and overhead bag fees entirely on short trips. Third, they book bags and seats at the time of initial purchase rather than adding them later, which almost always costs more.
Payment method matters too. Some budget carriers charge a processing fee for credit cards. Using a debit card or a fee-free payment option at checkout can shave a few dollars off the total. These patterns mirror the hidden costs that quietly drain everyday budgets — small charges that compound when ignored.
Finally, skip buying food or beverages on board. Prices on budget carrier flights are typically well above what you'd pay in the terminal, let alone outside the airport. Bring your own where policies allow.
