I have three active subscriptions for award booking tools (seats.aero.com, pointsyeah.com and awardtool.com) that help me find award space on flights (https://awardcracker.com/searching-for-partner-airline-award-space/). There are several other award search tools available, but I am only comparing the three programs in this review.

Seats.aero
The biggest pros are unlimited alerts for flights/hotels and a wonderful single/multi-airport or region based search capability from the same search bar (without the need to click on separate function tabs like Daydream Explorer or Panorama).
The typical multi-city pair search function limits results to +/- 28 days (see image below).
Has the ability to add +/- 180 days to search results between two regions (e.g., USA to India)
Once you add more than one region (from/to), the maximum flight search days with decrease to +/- 28 days (see image below).
The biggest cons of seats.aero are the inability to include domestic award connections and not being able to limit the flight duration in the search results (duration filter will be implemented soon as per Discord announcement).
PointsYeah
PointsYeah may not have any unique features compared to the competition, but it has the cleanest interface and should be the starter program for all points & miles enthusiasts (I recommend it to all my family & friends).
AwardTool
The biggest pros of AwardTool are the calendar view for results and flight connection time limiter (see images below).
Conclusions
All three competing premium award search engines each offer something unique over the other and I will continue to support the developers with their subscription. Whenever these programs improve their interface with new features, I will update the master comparison chart accordingly.
