Random information here because I'm too lazy to write an organized response:
-Try to get lvl 200 tickets. They are much better than field infield. Preferably on the 3rd base side so the sun isn't in your eyes. They cost the same as field infield tickets and give a better view and a lot more convenient than the lvl 100 concourse clusterf***s
-You could always buy a cheap 500 ticket, line up very early and grab a seat at the Alomar bar or the flight deck. Hope you have a strong bladder
-stubhub has a '100% guarantee' but it is very expensive. You can also try kijiji or https://www.reddit.com/r/jaystickets if you want to save on fees and USD conversion
