It's probably Jepp. They do custom NA plotting charts for airlines all over the world. Stacks of 'em in my office. Probably the only thing "custom" about them is the ETOPS alts. are highlighted that each airline is fond of using ,the range rings surrounding them and the airline's logo on the front. I would think that most airlines plan the same ETOPS alts., EINN, BIKR, etc. See if you can get a generic one from them and plot your own. Maybe check Sporty's?
