Do you prefer longer red eyes? after taking so many red eyes in the last few years, I’ve realized that redeye flights that are 12 to 14 hours are more enjoyable and more relaxing than red eyes that are 6-8 hours. If you were flying a legacy carrier such as Delta or even Singapore air when you get on a redeye flight, they often keep the lights on the first two hours so they can give you food and docart service . If the flight is only 6 to 8 hours that means that your sleep time has now been cut into and so you can only get like 3 to 4 hours of sleep before they wake you up again. on longer redeye flights that are between 12 and 14 hours after car service and food service you still have at least 6 to 7 hours when no one interrupt your sleep. Getting those extra hours of sleep really helps me with the jet lag as well as adjusting to the new time zone. Red eyes are enjoyable in general but short red eyes are in my opinion the roughest
