As a frequent traveler to Europe, I often ask myself this same question. The answer is really quite simple. An overnight flight allows airlines to make more flights in a day. This means they can increase the capacity of passengers they can serve.

There are few daytime flights between North America and Europe. This is for many reasons, including the length of the flights, big time zone changes, generally insufficiently large point-to-point traffic to warrant it, less productive aircraft (most have to remain overnight at one end), and so on.
Scientists who study sleep still maintain it's best to take an overnight flight because it may be easier to keep the body's internal clock, your circadian rhythm, synced. Night flight allows you maximize sun exposure during the day at your destination.
A jet lag rule of thumb says it normally takes one day per time zone to get back to “normal” (flying west to east). That means, after a nine-hour time change on a flight from the US west coast to Germany, you'll need nine days before your body fully adjusts to Central European Time.
One study claims it only takes two-thirds of a day per zone, or about six days to adjust to a nine-hour time difference (west to east). For westward flights it is somewhat easier to adjust to the time-zone shift, only requiring about half a day per time zone.
The benefit of a red-eye flight is that it maximizes your time both at home and at your destination — you're flying through the night rather than losing a day to travel. That often saves you the cost of an extra night in a hotel. Red-eyes are often cheaper than day flights, too, helping travelers save money.

As you're flying overnight, red eye flights act as both transportation and accommodation! Buying a red eye flight is a far cheaper option than arriving in the evening and staying in a hotel for the night.
Mostly (not all) pilots prefer night flying. Some pilots may love flying in the night while some may love to fly in the day. Here's how night flying is preferable to pilots: Some things are easier when it comes to night flying, some things are more difficult.
Nighttime or morning flights are statistically better for turbulence, compared to those in the day. Although turbulence can't be completely avoided at night, winds are often weaker and thermal convection turbulence is less, making the chances of encountering turbulence reduced.
According to a review in 2022, combining data from 18 studies, the longer you travel, the greater the risk of blood clots. The authors calculated there was a 26% higher risk for every two hours of air travel, starting after four hours.
It is widely acknowledged that jet lag is worse when travelling east, but this has nothing to do with the direction of Earth's rotation. Like many creatures, humans have a circadian rhythm that follows a 24-hour period and is kept in sync by the eyes' response to natural light levels over the day.
Limit naps in the days following your arrival.If you need it, taking a short nap can help you stay awake during the day. But napping for more than 30 minutes can keep you from falling asleep at night. Try to stay awake until your normal bedtime and get up on time the next day.
1 – Anticipate the time change for trips by getting up and going to bed earlier several days before an eastward trip and later for a westward trip. 2 – If you're wearing a watch, change the time to the destination time zone when entering the plane. 3 – Avoid drinking alcohol during your flight.
Melatonin is remarkably effective in preventing or reducing jet lag, and occasional short-term use appears to be safe. It should be recommended to adult travellers flying across five or more time zones, particularly in an easterly direction, and especially if they have experienced jet lag on previous journeys.
Jet lag symptoms usually occur within a day or two after traveling across at least two time zones. Symptoms are likely to be worse or last longer the farther you travel. This is especially true if you fly east. It usually takes about a day to recover for each time zone crossed.
