I spent $500 on a cross-country red-eye flight in Delta's basic economy. I'm glad I didn't upgrade to a premium class.

A Business Insider reporter flew from San Francisco to New York City on a Delta Air Lines red-eye flight in basic economy for $500, finding the seat comfortable enough for sleep and expressing satisfaction with not upgrading to premium classes. The flight, which lasted five-and-a-half hours, utilized a Boeing 767-300ER aircraft, and the reporter highlighted time-saving benefits of night travel.
