in an airplane
The weight of an airplane can vary widely depending on its size and model. Generally, commercial airplanes can weigh anywhere from 50,000 to 450,000 kilograms, which is equivalent to 50,000,000 to 450,000,000 grams.
Most people are surprised how much airplanes weigh, and engines too. Reciprocating engines typically weigh 1 pound per HP. Big jet engines weigh 0.2 pounds per HP or so and they typically weigh from one ton to several tons. Here a simulator for designing your own engine: http://www.grc.nasa.gov/WWW/K-12/airplane/ngnsim.htm
A semi-truck or a commercial airplane can weigh around 55,000 lbs.
A feather, a smartphone, and a pencil each weigh less than a kilogram.

No, weight changes but mass remains constant irrespective of the surroundings. :)
Airplane? What airplane? My paper airplane wings weigh less than 8 grams.

Stand on a scale. Figure out how much you weigh. Then pick up the airplane and stand on the scale. Subtract how much you originally weighed, and that is the weight of the airplane.
a bunch.
A paper airplane? A 747? Cessna?
A little bit less than a train made out of paper, but way more than a boat made out of paper. Of course, the size of the airplane wasn't stated in the question. If it was a really, really BIG paper airplane, it could weigh more than a teeny-tiny paper train. Although, if it was a tiny paper airplane it could weigh less than a HUGE paper boat. I'm pretty sure it would also depend on what kind of paper you use. A construction paper airplane would definitely weigh more than a tissue paper airplane. But one of those airplanes made out of copier paper would weigh about average. I wouldn't reccommend a toilet paper airplane. It would also depend on what kind of plane you were making out of paper. A 747 made out of tar paper is going to completely outweigh a Cessna made out of freezer paper. All in all, I would have to say a medium sized airplane made out of a mid-gauge paper would weigh in at around 3,982 kilograms.
lots of kilograms
Mountaintop is a compound word.
An airplane's weight ranges from under 1000 lbs to over 500 tons.

Atmospheric pressure is higher at sea level than on a mountaintop. This is because atmospheric pressure decreases with altitude; as you ascend, there is less air above you exerting downward force. Consequently, the air is less dense at higher elevations, resulting in lower pressure.
