I found a very similar tool, but with advanced functionality. You may see baggage allowance, aircraft model with the tail number on the route and flight schedule https://flightsmap.org
This is exactly what I need! I've been using Kayak and Kiwi to compare prices and routes, but it always takes a while to load.
Last month I got bumped from a flight SYD->AUH that was full of Hajj pilgrims, and now I have a 600 USD coupon for Etihad. I'm trying to fly to Auckland before the 19th of November, but I'm totally flexible about dates and transfer points on the way, as long as I can use that coupon.
I'll be making good use of FlightConnections to see where I can transit and how to get to Auckland via somewhere interesting!
I agree, useful site but the pop under windows are just annoying. They would put me off using the site again and I do think the site has value, just need to back off the spamming
