Why does a bag of peanuts appear inflated when flying on an airplane at high altitude?

Funny, I hadn't noticed that before. But if they appear inflated, it is because they are bagged and sealed on the ground, probably pretty close to sea level. However, the cabins of airliners are pressurized to 8000 feet. So the air pressure outside the bag, being lower than the pressure inside the bag, causes the air inside to expand and inflate the bag.

What happens to a crisps packet on an airplane?
Bags of chips (crisps) can expand in an airplane. A bag of chips on the ground doesn't appear to be inflated because the outside air pressure is high. As the elevation increases (like in an airplane) the outside air pressure decreases, which means that there is also less pressure in the bag. As the pressure decreases in the bag, the gas inside wants to take up more room and it expands (similar to what happens when the pressure is released from a can of soda). However, the cabins of most airplanes are pressurized, so you would not be able to see any expansion.
What will happen if you flip a coin in a high speed airplane and why?
Nothing unusual IF the airplane is flying level and at a constant speed. The coin will go up, flip, and come down as expected. However, if the airplane is accelerating...in ANY direction, the path of the coin will appear to be altered once it is in the air. For instance if the plane dives as the coin is thrown, the coin will appear to accelerate in the Upward direction.
