What should i take in my hand luggage?

Keep it to the minimum is the best idea. I always try to do this but if you want to use the hand luggage as part of your 'weight' allowance for your baggage then a change of clothes is certainly advisable in case your checked in bag is delayed. Essentials are:- Passport, ticket, money items such as cards travellers cheques and currency, travel insurance documents. Booking Invoice for your package holiday. House/car keys. phone You may need:- Tissues, pen, sweets, book, headphones for inflight entertainment. (the ones they issue/sell are not good quality) I would not bother with wet wipes, there are plenty of wash rooms at the airport and they always have them on the plane.

ipod, a book, pillow, hand sanitizer, extra outfit (just in case you know), cell phone(some work on planes, some don't), and a stuffed animal. It's four hours, you need company. :]

Definitely all of your money, credit cards, personal information, travel documents, etc. Anything of a personal nature that you couldn't afford to lose, pack in your carry-on. Take any electronics that you don't want stolen or broken, like laptops, cameras, cell phones, etc. Any prescription medication. A full change of clothes is a good idea, particularly if you have a layover. You can take snacks on board with you. Take things to entertain you and keep you busy, like books, word puzzles, music, etc.

The obvious is your wallet and all your traveling documents, Other than that. Some make up, toothbrush and toothpaste (just a small tube) a book or magazine, ipod, headphones, cell phone if you are bringing it, and one of those neck pillows if you have it.

iPod, Perfume/Make Up (You can only bring 100ml on plane) Water (Can't bring on plane) Money! Passport! A few magazines... Ooo a travelling pillow... That's about it.
