There is a report from USA Today on August 29, 2000 talked about Red-eye flight.
Red-eye flight means the flight that departs at midnight and arrives in the morning. And a statistic shows that more US travellers choosing the red-eye flight (especially West coast, due to time zones). For example: The load factor of United Airlines' red-eye flight was more than 80%, about 64% increases to the year before.
Will you take the red-eye flight? and how about travelling on a International red-eye flight?
