Booking cheap flights isn’t always about searching harder, it’s about knowing where the loopholes and traps are. In 2025, two things can drastically impact how much you pay for airfare: error fares and hidden fees. One could save you hundreds. The other? Cost you even more.
Here’s how to take advantage of mistaken fares and avoid the sneaky charges that airlines don't advertise upfront.
What Are Error Fares?
Error fares (aka mistake fares) are unintended, super-low prices caused by technical glitches, human error, or currency conversion issues. Think $120 roundtrip to Europe or $350 business class to Asia.Why They Happen:
- Data entry mistakes (e.g. missing a zero)
- Glitches in automated pricing systems
- Miscalculated fuel surcharges or taxes
- Currency discrepancies on international sales
Real examples:
- $199 roundtrip NYC–Tokyo on ANA
- $278 roundtrip LA–Rome on Air Canada
- $450 business class JFK–Paris via Qatar Airways

Will Airlines Honour Error Fares?
Short answer: Sometimes yes, sometimes no.- If your ticket is confirmed and ticketed, many airlines will honour it.
- If it's still "on hold" or pending, they might cancel it.
- US Department of Transportation protections have weakened, but public backlash still makes some airlines hesitate to cancel.
Best practices:
- Don’t call the airline—it might alert them to the mistake.
- Wait until your ticket is issued before booking hotels or add-ons.
- Use a credit card with travel protection just in case.
The Flip Side: Hidden Fees That Ruin “Cheap” Fares
Low base fares are tempting, but what you don’t see can cost you more than the flight itself. Many airlines, especially low-cost carriers, rely on ancillary fees to boost profit.Common hidden fees to watch out for:
- Checked bags: $30–$100+ depending on route and airline
- Carry-on bags (on budget airlines): Sometimes $20–$50
- Seat selection: Aisle or window seats can cost $10–$60
- Booking fees: Especially from third-party OTAs
- Airport check-in fees (hello, Ryanair-style airlines)
- Change/cancellation fees: Often $75–$200 on non-flexible tickets
Example: A $59 base fare on a budget airline could easily become a $180 total after adding bags, seat, and fees.
How to Avoid or Minimise Extra Charges
- Always check what’s included in the fare class before booking.
- Travel light by using a cabin-sized rucksack or compact suitcase within strict airline limits.
- Check in online and use mobile boarding passes to dodge airport check-in charges.
- Book direct with the airline when prices are similar, it gives better support if plans change.
- Use airline loyalty or co-branded credit cards since some include priority boarding or free seat selection.
- Compare bundle vs à la carte options—sometimes the “Plus” fare actually saves you more.
Final Word: Play It Smart, Not Just Cheap
Error fares are rare but magical. Hidden fees, on the other hand, are designed to make “cheap” look cheaper than it really is.To stay ahead:
- Be ready to book mistake fares without hesitation
- Always read the fine print
- Compare total costs—not just base fares
In the battle between airlines and your wallet, the best tool is knowledge. And with the right tools and tactics, you’ll fly smart and save big.
