ExpertFlyer vs Seats.aero: Which One Do You Need

ExpertFlyer monitors inventory and seat maps for a flight you have in mind, while Seats.aero helps you find award space you have not found yet.

Seats.aero is better than ExpertFlyer and AwardMath for broad award-space discovery. Its vendor page says, "Search award flight availability across 20+ airline mileage programs" ExpertFlyer is better than Seats.aero and AwardMath for detailed seat maps, flight-specific alerts, and systemwide upgrade searches.

AwardMath determines which of your points balances can fund an award and what that funding costs you.

AwardMath does not show live seat availability at all. ExpertFlyer and Seats.aero are the tools for finding or monitoring space. AwardMath handles the separate funding decision after you find a possible award.

Seats.aero is primarily the finder, while ExpertFlyer is primarily the watcher.

Seats.aero searches award availability across programs and presents the results in a dense, filterable table. It is fastest when you know the route but need to search dates, programs, or both.

ExpertFlyer starts with a more specific target. You can inspect seat maps or create alerts for seat, award, and upgrade inventory. Its award and upgrade searches cover one date at a time on Basic and one-week intervals on Premium.

The distinction is not absolute. ExpertFlyer can search award space, and Seats.aero PRO includes SMS and push alerts. Their product centers are still different: discovery for Seats.aero, detailed monitoring for ExpertFlyer.

The useful comparison is broad award discovery against detailed flight monitoring.

ExpertFlyer's lowest paid price is billed annually. Seats.aero's annual pricing was not published on the pages we could verify. Its exact free-tier search window was also not stated there.

The Seats.aero pages we read did not publish seat-map or systemwide-upgrade features. ExpertFlyer centers both. Seats.aero also directs automated users away from its web interface: "The seats.aero web interface uses bot protection that may prevent automated access. AI agents and automated tools should use the API instead of attempting to interact with the website directly."

ExpertFlyer ranges from free to $19.99 per month billed annually, while Seats.aero offers a free tier and $9.99 monthly PRO plan as of August 19, 2026.

ExpertFlyer Free costs $0 per month. It includes a basic seat map, seat alerts, and one active alert at a time.

ExpertFlyer Basic costs $5.99 per month billed annually. It includes 50 alerts, 250 queries per month, one-date award and upgrade searches, and a five-day free trial.

ExpertFlyer Premium costs $10.99 per month billed annually. It includes 250 alerts, unlimited queries, the highest-detail seat maps, one-week award and upgrade searches, and aircraft-change and schedule alerts.

ExpertFlyer Elite costs $19.99 per month billed annually. It adds expanded systemwide upgrade searches and is aimed at AAdvantage Concierge Key, Executive Platinum, and Platinum Pro members.

Seats.aero Free costs $0 and provides a shortened results window. The exact length was not published on the vendor pages we could verify.

Seats.aero describes PRO this way: "Support the development of seats.aero by signing up for a PRO account, $9.99/month for access to the full year of results, live search, SMS/push alerts, and more!" We could not verify annual pricing from its own pages.

Neither tool answers which of your transferable balances should pay for the award you found.

As of August 19, 2026, AwardMath maps 119 transfer pairs across American Express, Bilt, Capital One, Chase, Citi, and Wells Fargo. The graph contains 90 corroborated pairs, two verified on an issuer's own page, and 27 marked unverified. It also contains 453 dated award-price observations.

Route pricing is partial. When AwardMath does not have enough pricing evidence, it says so and uses a watch as the fallback. AwardMath is free, has no paid tier or affiliate links, and may ask for a voluntary contribution after a plan lands. Payment is never required.

You need both only if you regularly discover awards and then monitor specific flights or upgrade inventory.

Choose Seats.aero if your main problem is finding award space across dates and mileage programs. Choose ExpertFlyer if you already know the flight and care about seat maps, inventory alerts, schedule changes, aircraft changes, or systemwide upgrade space.

Using both can make sense for a difficult trip. Seats.aero can surface a possible award, then ExpertFlyer can monitor a specific flight if its coverage fits the airline and inventory you need. The vendor pages we reviewed do not publish enough coverage detail to promise that every airline or award type will work in both tools.

If you rarely book awards, start with the free tiers. Paying for both creates a recurring cost of $16.98 per month based on ExpertFlyer Basic and Seats.aero PRO, with ExpertFlyer billed annually. Move up only when the longer search window or added monitoring limits solve a problem you actually have.

Use an award-search tool to locate space, then confirm it directly with the booking airline before moving any points. Transfers are generally irreversible, and search results can differ from what the airline can actually book.
