seatmoa Maps the World of Mileage Seats

Field notes

The service combines departure and destination ranges rather than limiting users to a single city pair. Its visible model checks the outbound and return directions separately, supports open-jaw routing, and uses the smaller connected seat count when presenting bookable capacity. The page lists 86 major airports and identifies Flying Blue as an example program. A free tier covers selected-date searches and two alerts, while the stated Plus plan expands date coverage and notifications.
