I've been all around Europe, so I have experience with planes... The sensation of taking off is very fun; everything abruptly becomes weightless for a second, and yet you're pushed into your seat with an incredibly strong force.
If you're lucky enough to get a seat by a window, the first hour of flight or so allows you to look down at the world as you travel; it's very memorable, how geometric and tidy the city lights look from above, and how it looks as if you could hold an entire world in your hand.
That said, the plane usually rises above the clouds at some point, and there's nothing to see other than the Sun, the Moon and a thick blanket of white down below.
The myth about airplane food being mediocre is true. The snacks are tolerable, though.
When you're in a plane, you go to very high altitudes. Most planes are oxygenated, but even so, the air at these heights is so thin that it causes hypoxia, especially in first-time passengers (if you fly a lot, your body eventually adapts). You'll probably stop being able to hear things as your eardrums suffer tinnitus, you'll feel super nauseous and tired, your thoughts will get fuzzy... That's what happened to me, as I am a lowlander.
Snow... It is mundane to me, so I do not know what to say about it. The white snow is nice and gives the world a very "pure" appearance, but I recommend not touching any of the yellow snow if you ever come across it.
