Flight paths are mapped out before aircraft take off, depending on the shortest and most efficient route, and flight paths can even change during flight depending on weather, wind and jetstreams, to name just a few variable factors.

Most airlines use a Preferential Bidding System to determine routes. Basically, pilots submit which routes they want to fly (based on location, schedule, etc.)and then a system assigns them routes, with more senior pilots having preference on getting their choices.
Most airlines change the schedule during the spring forward and fall fallback times. And perhaps also at the beginning of summer and beginning of December. They often finalize those changes about 3 months prior to those dates. That's the general guidelines, with tonnes of exceptions.
Do pilots actually fly the planes? Pilots typically fly the plane during take off and landing. The pilot manually controls the plane until it reaches the required height.
Some crews talk a lot with each other, while others remain quiet for much of the flight. If pilots share a lot in common and enjoy discussing mutual topics of interest, an entire multi-day trip can be filled with conversation.
Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.
Aircraft with fixed wings cannot stand still in the air, unless we are talking about VTOL (Vertical Take Off and Landing) aircraft. Lift is created by air flowing around the wing. Too little forward speed, and the wing will stall (loose lift).
Curved routes are preferred by aircraft because they are less likely to encounter obstacles and use less fuel than straight ones. Since a curved path covers more ground than a straight one, it provides additional options for emergency landings.
Flight plans need to account for the curvature of the earth when they are created. Since the earth is three-dimensional, it would be impossible not to fly in an arc. Another reason that planes would choose to fly in a trajectory that resembles an arc is to account for the amount of traffic that will be in the air.
A: The tracks across the Atlantic are determined daily to take into account the meteorological conditions of the moment. If there are strong winds, the eastbound tracks will be farther north to take advantage of them, while the westbound flights will be routed south to avoid the headwinds.
The simple answer is yes, pilots do, and are allowed to sleep during flight but there are strict rules controlling this practice. Pilots would only normally sleep on long haul flights, although sleep on short haul flights is permitted to avoid the effects of fatigue.
Fatigue is particularly prevalent among pilots because of unpredictable work hours, long duty periods, circadian disruption, and insufficient sleep. These factors can occur together to produce a combination of sleep deprivation, circadian rhythm effects, and 'time-on task' fatigue.
Many airlines provide crew rest areas on their aircraft, where pilots can sleep during long-haul flights. These areas are usually located in the tail, cargo area or above the cabin of the plane and are designed to be as quiet and comfortable as possible. Other crew members prefer to use business class seats to rest.
Some airlines compensate pilots for significantly long times between flights (usually two hours or more), but this time is only partially paid. The 30-45 minutes spent in the cockpit prior to push is not usually paid, which has a significant effect on the overall pay of pilots who operate short flights.
Long-haul pilots will fly one leg to another country, layover for a day or more, and fly back. Most pilots will work for four days and then have three days off. This results in an average of 15 days off a month.
Specifically, plane tickets usually don't get cheaper closer to the departure date. Instead, flights tend to be the most inexpensive when you book between four months and three weeks before your departure date. According to CheapAir.com, you can expect rates to go up after that period.
Can an airplane stay up in the air without moving forward just like helicopter? A: Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare.
In the United States, airlines are not allowed to keep passengers on the tarmac for more than three hours on domestic flights and four hours on international flights without allowing them to disembark. After this time, the airline must either return to the gate or provide alternate transportation.
Don't wait until a few days or weeks before departure thinking you can score a last-minute deal. Airlines typically hike up flight prices in the days and weeks before departure – when they know business travelers and desperate flyers will pay whatever it takes to get where they need to go.
