I did some playing around with ChatGPT to help me program a scrapper to get all of these AONEx fares from ExpertFlyer.

For reference, see below the top 30 list. Some definitions

• This is with JL as ticketing carrier. I have checked with AA as well and there weren't any noticeable differences, but didn't check in detail / check all ticketing carriers (I plan to do that later).
• All prices are in USD
• I sometimes included multiple airports in the same country as I wasn't sure if they would price differently (they don't, pricing appears to be by country)
• I ranked them by increasing AONE6 fares. The ranking is not 100% the same for all the fares (e.g. DEL is cheaper than KUL for AONE3 but more expensive for AONE6), so you should check for what you want
• I have added points in various continents as I was trying to find where to start (ideally I would have liked to start in Americas as I don't care as much about US flights but wanted to maximize Asia / EU-DOH segments). Sadly Americas is by far the most expensive
• Note: Cairo has really been priced to death. It now ranks last on the list, at almost double the prices of ex-Japan...

I'd be happy to do the same for DONE if people find this helpful, let me know
