Key takeaways
- Secret Flying is a free, global feed of deals and error fares - broad, high-volume, and the same for every reader.
- Snagfly is wishlist-based: you pin destinations and it watches only those routes, alerting at ≥50% below the verified 90-day median.
- The trade-off: Secret Flying gives you everything and lets you filter; Snagfly gives you only what's relevant, capped at three a week.
- Best fit: Secret Flying if you're flexible and love browsing deals; Snagfly if you already know where you want to go.
How Secret Flying works
Secret Flying is a website and app that publishes flight deals and error fares as its team (and community) finds them, sorted by departure region. It's free, it's global, and it's genuinely great at surfacing dramatic mistake fares fast. The model is broadcast: everyone sees the same feed, from every origin, to everywhere. That's its strength - and its catch. You'll scroll past a lot of deals from cities you don't fly from, to places you weren't planning to go, and it's on you to spot the one that fits.
How Snagfly works
Snagfly starts from your destinations, not a global feed. You pin the places you actually want to fly to, and its AI watches only those routes 24/7. An alert fires only when a fare drops at least 50% below the rolling 90-day median for that route - many reach up to 90% off - and email is capped at three a week, one a day. You book directly with the airline. It's $29.99/year ($2.50/month, billed annually) after a free 7-day trial.

Where Snagfly has the edge
Only what you'd book
Every alert is for a destination you pinned - not a deal from a city you don't live in to a place you don't want to go.
A verified bar
≥50% below a real 90-day median. Secret Flying curates well but publishes no baseline you can check.
A capped inbox
Three alerts a week, maximum. The feed never floods.
Book direct, no markup
Snagfly links you to book with the airline and takes no commission.
Where Secret Flying might suit you better
To be fair: Secret Flying is free, and if you're wide open on destination and enjoy scrolling a global deal feed, it's hard to beat for sheer volume and for the biggest, wildest error fares. If discovery is the fun for you, that's a real draw. The trade-off is that relevance is your job - you'll do the filtering, and the deals aren't tied to a wishlist or a published baseline.
Should you choose Snagfly or Secret Flying?
Choose Snagfly if you already know the destinations you want and would rather hear only about those, at a fare you can verify, without the flood. Choose Secret Flying if you're totally flexible and love browsing a free firehose of global deals. Plenty of travelers use both - Secret Flying for open-minded inspiration, Snagfly to make sure the routes they actually care about never slip past.
