When traveling on long journeys, sometimes it feels like the hours are just dragging by. But using some of these steps, you can kill time.
Get a pen and some paper. You can use these simple things to play all kinds of games such as Tic-Tac-Toe, Hangman and many more. If you don't have anyone to play with, try doodling. Also, try to find a small, fold-away travel game such as chess, which you could play with someone else.  X Research source
Bring magazines or newspapers along or read the in-flight magazine or sales catalog if you're on a plane.  X Research source
Bring along an MP3 player or iPod and listen to your favorite songs. On long and crowded plane or coach trips, you could use music to drown out background noise and help you get to sleep.  X Research source
Bring a portable DVD player to watch a movie.
Bring a portable gaming system or cell phone to play games. If you are a gamer, buy a new game or two before you go and start them during the trip.
Bring your laptop. It is perhaps one of the best items to take, as you can do so many things on it.
Do some crosswords or puzzles. Not only will you pass time, but you will also be exercising your brain.
Look out the window and enjoy the scenery.
Sleep! It is the best way to pass time, especially on long flights.
Count the number of a certain thing as you travel if you're in a car. (yellow cars, fast food restaurants, Volkswagen's, or license plates from different regions) If you're in an airplane, count how many people walk down the aisle, count the clouds, etc.
Play car games like the "ABC" game where you try to find each letter alphabetically as you travel on (i.e. signs, license plates, anything outside your car or vehicle).
Listen to an audiobook. If you love a good story but reading makes you feel carsick, or if you're the one driving, this is a great alternative.  X Research source
Have a conversation with someone you are traveling with.  X Research source
If you are the driver, get a CD of a musical and sing along to the entire show. It passes at least an hour and you can work on your vocal and acting talents!
While listening to your MP3 Player, picture the singer (or if you don't know what the singer looks like, make one up) in the window singing the song. Use your imagination, picture them running up to the car, or just singing without moving. Your friends won't even know!
Play small pranks on people you are traveling with.
