Don't miss out on the first-class upgrade if you qualify for it
"I think it's great we don't have to travel in suits and high heels anymore. You can be comfortable. But you can also be classy and comfortable. Check your air carrier's rules — there are still dress codes sometimes in first class and, who knows, maybe, miracle of the day, you'll get that cheap upgrade to first class. Be comfortable, but if you can avoid wearing your pajamas, that's great."
