ALL true, thanks.
As do I... I've been taking the subway alone since I was 10 or 12 yrs old. Use public transportation in many cities I travel to but at some point, cost/convenience comes into play or the "so called in logic 1/ 0 implication"
Try upfront, either mileage upgrades, mileage tickets from airline or credit card points....or what I've been doing for the past few years, buy the ticket FROM Asia or that side of the world- roundtrip, they're usually cheaper than buying FROM North America 🤔
