1. International Airline Pilots speak English.

2. Flights longer than 8 hours require 3 pilots(1 captain and 2 first officers) to rotate flying duties. Flights longer than 12 hours require 4 pilots (1 captain and 3 first officers). They usually fly 3-4 hour shifts.

4. The normal ratio of Flight Attendants to passenger seats is one Flight Attendant for every 50 passenger seats.
5. The height requirement for Flight Attendant is for safety reasons, making sure that all flight attendants can reach overhead safety equipment.
6. The normal ratio of Lavatories to passengers is approximately one lavatory for every 50 passengers
7. Singapore Airlines spends about $700 million on food every year and $16 million on wine alone. First-class passengers consume 20,000 bottles of alcohol every month and Singapore Airlines is the second-largest buyer of Dom Perignon champagne in the world.
8. KLM of Netherlands stands for Koninklijke Luchtvaart Maatschappij (meaning Royal Dutch Airlines)
9. KLM is the worlds' oldest airline established in 1919.
10. QANTAS Australia's national airline originally stood for Queensland And Northern Territories Air Service. QANTAS is the second world's oldest airline established in 1920.
11.QANTAS still has the world's best safety record with no crashes as of 2011.
12. Virgin Atlantic lists catering as their third biggest expense, after fuel and maintenance.

13. American Airlines spent about $425 million on food for domestic passengers in 2001.
In-flight catering is an $18 billion worldwide industry employing up to 200,000 people.
14. An air traveler can lose approximately 1.5 liters of water in the body during a three-hour flight.
15. The white trail a plane leaves in the sky can be used to predict the weather.
The contrails planes leave behind are made of water vapor. A thin, shorter-lasting tail indicates low-humidity air and fair weather. A thick, longer-lasting tail could signify the early indicators of a storm.
16. "Blunder Trophies" used to be given to pilots who made ridiculous mistakes.
The National Museum of the US Air Force displays "Blunder Trophies" from the 1920s and the early 1930s presented at the McCook and Wright Fields. These trophies were given to silly pilots who made mistakes like taxiing into a parked airplane or taking off without enough fuel.
17. There's a secret lock on the outside of an airplane bathroom that will allow flight attendants to unlock the door if passengers were to lock themselves in.
18. Most flight attendants don't turn their cell phones off after they ask the passengers too.
19. In the U.S.A., over two million passengers board over 30,000 flights each day.
20. The air you breathe on an airplane is actually compressed air taken from the engines. A large portion (25% to 50%) is blown in the flight deck, the rest is for the passengers. The air leaves the airplane via a small hole in the back of the fuselage."
Boeing's website explains that air from the engine’s compressors helps to warm and pressurize air from outside the plane. This treated air is then circulated into the cabin for you to breathe.
21. One of the most deadly airplane accidents actually happened on the ground. In 1977, two fully loaded planes carrying a total of over 600 passengers collided head-on in the middle of the runway in what is now known as the Tenerife Accident, named after Tenerife Island where the accident occurred. Over 500 people died.
22. Flight Attendants: Seniority Means Shorter Skirts.
Our tenure on the job doesn’t just determine which routes we fly and which days we get to take off; it also affects the hierarchy in our crashpad, an apartment shared by as many as 20 flight attendants. Seniority is the difference between top or lower bunk, what floor your bed is on, and just how far away from your room is from noisy areas such as doors or stairwells.
23. Aspiring commercial pilots generally invest more than $70,000 in their education and clock an average of 4,000 hours of experience before they are hired by Air Canada.
* Once their flight simulator training is complete, pilots move directly to piloting fully-loaded passenger airplanes. They are, however, accompanied by line indoctrination pilots for their first few flights. After a second test by a supervisor pilot, they’re fully cleared to fly on their own.
* Pilots are sent back into the simulator at least every eight months to renew their license; every six months for those who command the Boeing 777.
* Pilots can fly only one type of aircraft at a time. Before acquiring a license to command a different model, they must go through 8 to 12 weeks of training. The process includes “ground school”, pre-simulator mockup flights and simulator training.
* Pilots may spend long periods of time away from home. To keep their loved ones close, they’ll often keep photos of their family or spouses in the inside lining of their hat.
* Pilots aren’t allowed to share food. As a safety
precaution, pilots order and eat different crew meals while on the flight.
24. All Boeing 777 Commercial Jets Are Equipped With Explosion-Proof Black Box Recorders And Can Transmit Location Data For 30 Days.
These black boxes are designed to withstand any explosion from the plane itself. The bomb-proof structures hold digital recordings of the conversations in the cockpit and also detailed flight data and control surface data. The reason why investigators are having such a hard time finding the aircraft is that they cannot pick up any signal from its black box recorder. Usually, homing in on the signal leads to the plane itself, but the absence of any signal means that the black box, a device meant to withstand explosions, has vanished, malfunctioned or been destroyed by some unfathomable power.
25. There Are Parts of Aircraft That Are Buoyant And Naturally Float On Water.
In past cases when a plane crashes into the sea, many parts of the plane are found floating on the surface because they are buoyant. No such debris has been found yet, which has baffled search and rescue teams even more. Even if there was an explosion on board while the plane was in mid-air, the debris would have fallen over a much greater area and more easily spotted.
