I’m living in Asia and when I need to fly I’ll just buy a meal at 7-Eleven or Family Mart to bring on the flight. It’s amazing how these convenience stores can make good quality food so cheap but the airlines somehow can’t provide.
Business class is rarely worth it, it’s not priced for mere mortals. Most people have a corporation buying their tickets, or are using air miles to reduce the price, or they are 1%ers, etc.
