the puffy whiteness of clouds against the background of the earth or sky

While I dislike greatly the "traveling" part of travel, as in the hassles of getting to the airport, the possibility of delays, missed flights, cancellations, and re-booking... I do like very much the actual "flying" part of travel. I like a window seat and also happen to be one of those geeks who likes to take photos of the clouds out of that usually dirty, little porthole, that doubles as a window. 

I like rising into the clouds, getting above the clouds, and especially being sandwiched between layers of clouds. 

Sometimes you can catch a sunrise or a sunset which can be glorious, but I am equally happy with the puffy whiteness of clouds against the background of the earth or sky.
