Blue ice, in the context of aviation, is frozen sewage material that has leaked mid-flight from commercial aircraft lavatory waste systems. Airlines are not allowed to dump their waste tanks in mid-flight, and pilots have no mechanism by which to do so; however, leaks sometimes do occur.
Actually, most, if not all, modern commercial aircraft can land with full tanks and at full max takeoff weight. As others have said, many modern airliners don't even have the capability of dumping fuel and burning off fuel can be a long process often the overweight landing check can be completed faster.
A plane like a Boeing 747 uses approximately 1 gallon of fuel (about 4 liters) every second. Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters). According to Boeing's Web site, the 747 burns approximately 5 gallons of fuel per mile (12 liters per kilometer).
According to the Airline Monitor, an industry publication, a Boeing 737-800 burns 4.88 gallons of fuel per seat per hour.
As of Monday afternoon, Jet-A is selling to corporate jets for an average of $5.21 per gallon. (Fuel is usually more expensive on the coasts and cheaper in the Midwest.) Because the cost of Jet-A closely tracks the price of a barrel of oil, fuel costs for private jets have quadrupled since 2000.
The price of jet fuel as of January 2015 is as follows: 170.8 Cents (US dollars) per Gallon. 1 litre = 0.3125 pence (pound sterling) 1 litre = 0.40 Euros.
Yes, you can safely land with full fuel. There are many Boeing 767 and Airbus A300, A310, and A330 that no not have fuel dumping capability. They just land overweight in case of an emergency and then do an overweight landing inspection.
This fuel is expensive for a number of reasons: The lead itself is expensive. 100LL fuel has many more "aromatic" hydrocarbons than mogas (auto fuel) in order to increase the octane levels and prevent fuel from vaporizing in your lines at high altitude. It's much higher grade, so it costs more.
Fuel is stored in a number of tanks located at differnt parts of the plane. Majority of the fuel is stored inside the wings and between the wings to maintain Center of Gravity. Also, storing fuel inside the wings reduces wing flutter and provides rigidity upto some extent. This is the fuel tank layout of a B747–400.
Jet fuels are typically made by blending and refining various crude oil petroleum distillation products such as naphtha, gasoline, or kerosene in order to meet specific military or commercial specifications (Air Force 1989b).
Jet fuel is a clear to straw-colored fuel, based on either an unleaded kerosene (Jet A-1), or a naphtha-kerosene blend (Jet B). Similar to diesel fuel, it can be used in either compression ignition engines or turbine engines.
The standard fuel used in aviation piston engines is aviation gasoline, or AvGas. Aviation diesel engines are an abnormality in the piston aircraft fleet, as the technical challenges associated with building lightweight aircraft diesel engines are substantial.
Q: About how much fuel per hour does a medium-sized aircraft such as the 737 burn? A: In round numbers, a 737 will burn 5,000 pounds (750 gallons) an hour. These are approximate figures, and the conversion between pounds and gallons is conservative.
Jet fuel can actually be used in cars, but only in diesel engines. Kerosene jet fuel and diesel are actually similar enough to allow for cross-functionality and would provide a similar performance. Both are derived from crude oil, and both run their respective engines on combustion.
During takeoff for a long flight, a large commercial plane can be carrying tens of thousands of gallons of fuel, which (at about 6.7 pounds per gallon) can translate to hundreds of thousands of pounds of fuel [source: Conte].
A 747 can seat 380 to 560 people, depending on how an airline sets it up. A full one is a moneymaker. But an airline that can't fill all the seats has to spread the cost of 63,000 gallons of jet fuel -- roughly $200,000 -- among fewer passengers. The jets also are too big for most markets.

An average flight on an American Airlines 737-800 costs $5308 per hour. The plane burns 850 gallons per hour. Fuel costs $4,156 based on Jet-A fuel costing $4.89 a gallon. A cockpit crew of two along with five flight attendants costs around $465 an hour.
The Boeing 747 burns approximately 10 to 11 tonnes of fuel an hour when in the cruise. This equates to roughly 1 gallon (approximately 4 litres) of fuel every second. It can carry up to 238,604 liters of fuel. It has a range of about 7,790 nautical miles.

How many ton in 1 gallon [U.S.] of kerosene type jet fuel? The answer is 0.033986615678776.
Fuel dumping (or a fuel jettison) is a procedure used by aircraft in certain emergency situations before a return to the airport shortly after takeoff, or before landing short of the intended destination (emergency landing) to reduce the aircraft's weight.
If a plane runs out of fuel, or you chop power to the engines, it becomes a glider. If a plane runs out of fuel, or you chop power to the engines, it becomes a glider. The glide ratio of a Boeing 747 is averaged at 17:1. This means that for every 1,000 feet of altitude lost the plane will travel 17,000 feet.
Dumping Fuel Before Landing Lowers Its Weight
They don't do it before or during takeoff, nor do they do it halfway through their flight. Rather, airlines may dump some of their airplane's excess fuel immediately before landing so that it lowers the weight of their aircraft.Even as late as 2002 airlines such as Aeroflot, Condor, Iberia, and Garuda still allowed smoking on some flights. Go back further and you'll see that not only was smoking permitted on airlines, but encouraged. SAS, for example, manufactured its own cigarettes!
Water salutes have been used to mark the retirement of a senior pilot or air traffic controller, the first or last flight of an airline to an airport, the first or last flight of a type of aircraft, or other notable events. When the Concorde flew its last flight from John F.

Yes it can, but it is not designed to do so, and an emergency landing is always better on land at an airport. However, as long as sea conditions are smooth and the ditching is performed in a proper way, an aircraft can land on the sea and remain afloat.
An average flight on an American Airlines 737-800 costs $5308 per hour.

AP On Wednesday, a Boeing 777-300 operating as Emirates Flight EK521 crash-landed and burst into flames at Dubai International Airport after declaring an emergency. Emirates has confirmed that all 300 passengers and crew members aboard the flight are safe.
