Error fares vs sale fares in 2026 — how they differ, cancellation risks, and a booking checklist with links to the mistake fares complete guide.
What is the difference between error fares and sale fares?
Sale fares are intentional airline or OTA discounts with published rules and typical honour rates. Error fares — mistake fares — stem from pricing glitches; airlines may cancel tickets though many honour them after delay. Sale fares trade absolute price for predictability; error fares trade risk for occasional extreme discounts.

What error fare and sale fare mistakes cost travellers money?
Costly errors include booking non-refundable hotels instantly on mistake fares, assuming EU261 applies to cancelled error tickets universally, and posting live errors publicly — which can kill honour chances. Sales mistakes are milder: ignoring bag fees and bad connection times. Screenshot fare rules at checkout either way.
Posting on social media can alert airlines to pull errors faster.
