So my 60l fill will get me 20 AP points on this option. I would have to fill up, and enter that number, every single day for three years to get enough points for a decently priced domestic return in Y. It would be every single day for 10 years for a typical decently priced return in Y to Europe, the sort of fare you can often buy for about $800. This does not leap out as a good use of my time but ymmv.
