Compare Flight Theoretical Redemption Costs
Awardhacker.com shows theoretical saver level award pricing between two cities, this is based on flight schedules; good
http://www.milez.biz shows theoretical save level award pricing, but also contains helpful routing tips, 15 searches per month free then paid
https://www.travelcodex.com/award-maximizer/ shows theoretical saver level award pricing between two airports, pricing is based on award chart, not as accurate for distance-based charts
http://welltraveledmile.com/comprehensive-infographic-and-table-comparison-of-major-airline-award-charts/ a couple of years out of date, graphic view of award costs, less useful with many programs having variable award rates and not the chart from when this was published
http://wandr.me/Award-Search/Avios-Map/ tool to see what routes you can book cheap Avios distance awards from, please note this outdated and there are no more 4500 mile awards in the US, RIP
Resources to Find Award Availability
https://seats.aero/ Last minute award flights a limited number of programs and select airports, can set alerts, free, dev active in this community (new name)
https://straighttothepoints.co/ Economy flights are free, business is paid alerts. A little different than some of the others give dates and it gives destinations.
https://www.seatspy.com/ paid resource, can search up to a year at a time, fewer airlines than some other tools. Nonstop only; good to find availability on a specific route with flexible dates.
https://awardlogic.com/ lets you search for free and tells you the price, but blocks out the program, you can often figure it out and it lets you know simply if there is a cheap option. Full source is paid. Good for specific dates with 20+ airlines. I often use the free version to see if there is any base award availability and since it gives Chase Portal pricing I get an idea of the cash price too.
https://www.cowtool.com/ Searches Air Canada (Star Alliance) award availability on multiple dates, origins, and destinations, free, but requires registration
https://rewardflightfinder.com/ search for British Airways flights between two destinations, free account gives year-long view with number of seats and miles price per class, nice formatting
