Quick overview: what these tools do

SeatSpy focuses on showing one year of award availability for a curated list of specific airlines (Air France, KLM, British Airways, Virgin Atlantic, American, etc.). It displays a visually appealing outbound/inbound award calendar and lets you create alerts for exact origin/destination and date ranges.

Seats.Aero aggregates award availability across many programs and gives you a broad “haystack” of results you can filter into neat piles. Its Explore and Search features let you scan large regions (e.g., North America → Europe) and filter by award program, cabin, airport, dates, and transfer partner.

SeatSpy: what I liked (and what’s limited)

SeatSpy’s main value is its one-year calendar visual that shows round-trip award availability side-by-side—very handy when piecing together outbound + inbound legs.

• Calendar view makes round-trip planning intuitive.
• Alerts can notify you when specific award seats open up.
• Great if you only care about award seats flown by the tracked airline itself.

Important limitation: SeatSpy tracks the airline’s operated flights, not the award program. That means it won’t show partner-operated award space that’s bookable through another carrier (e.g., Delta flights that appear in Air France/KLM award inventory). That narrow focus reduces its usefulness for complex partner redemptions.

Seats.Aero: why it’s so powerful

Seats.Aero is the more comprehensive tool. The Explore feature gives a continent-to-continent view of award flights available within a single award program e.g. Flying Blue, and the Search feature lets you check months of availability across many programs at once. The free version of this tool only lets you look at award availability within the next 60 days. With the Pro subscription, you get a full year of award availability as well as extensive filters to organize your results.

Seats.Aero is especially useful for hunting “sweet spots” like Japan Airlines business class awards bookable with American Airlines miles, or Qatar Qsuites bookable with various transfer partners. [See a newer Beta feature that helps you compare transfer partner prices in one click]

It’s important to note that these results are “cached” meaning that the award availability was found at a previous time as indicated by the “Last Seen” column – handy for triaging stale vs. live results – make sure you verify award availability on the airline’s website before transferring your points to that program.

Costs, trials, and alert rules

Both tools use a freemium model, but the differences matter:

• SeatSpy: 5 free searches, then a two-week trial. Paid tiers: $3.99/month (limited to 4 simultaneous alerts and hourly alert cadence) or $9.99/month (unlimited alerts + instant alerts).
• Seats.Aero: Always-free 60-day rolling availability window with unlimited alerts in that window. Full-year availability + unlimited alerts costs $9.99/month for the Pro tier.

Speed test & practical notes

On a direct comparison (DFW ↔ Paris using Flying Blue inventory), SeatSpy took ~10 seconds to render the award calendar and Seats.Aero ~7 seconds to produce an equivalent table (including the extra click to view the full year). SeatSpy occasionally surfed up dates that weren’t immediately visible in Seats.Aero’s Explore results, though they did appear via Seats.Aero’s search tool.

So: SeatSpy is prettier and sometimes finds a few odd results. Seats.Aero is faster and far more flexible.

Which should you choose? My verdict

If you’re paying up to $10/month for one of these tools, go with Seats.Aero. It covers more award programs, offers richer filters, and helps you discover sweet spots across multiple airlines and partners. That said, there is a narrow use case for SeatSpy’s $3.99 tier: if you only care about Air France or KLM business class alerts or with other programs supported by SeatSpy and want a simple year-round calendar pushed to you, SeatSpy can be useful and cheaper.

In short: Seats.Aero wins for most people, but SeatSpy has a budget-minded niche.

What these tools won’t do for you

Neither tool replaces travel experience or knowledge. They can’t always piece together every connecting itinerary or show partner availability that isn’t being followed. For example, searches from some smaller origin airports (like Austin → Rome) may not appear as expected in either tool’s results—even though award inventory exists and can be booked via specific programs for great rates (e.g., 17,500 points + fees on certain carriers).

This is one of the few problems with relying on award search tools. Here’s how to identify and combat these issues.

Final thoughts

This Seats.Aero vs. SeatSpy Review shows both tools have value. Seats.Aero is the more capable and fun-to-use tool for hunters of award sweet spots; SeatSpy offers a clean calendar and a cheap route for very focused users. Try the free trials, experiment, and use the tool that complements your travel knowledge and goals.
