Sorry, I now realized I forgot to put the carrier. It was on CO/UA.
SLP-MIA was 250USD, not a good MR but good because it is a very good price for this route. I am trying to get to *G with CO/UA...currently have 15000 miles in January and another 12000 in february. I am *S with CO.
I am looking something from MEX/GDL/SLP/BJX to ORD/SFO to maximize the mileage. and maybe inside this RT from that city another MR as I did it in January.
I was happy with the bump in SFO so SFO/ORD route and SFO/LAX routes are among my favourite routes to take. After reading that these routes have frequently bumps.
