Easy tricks for cheap flights

Flying now could not be as expensive as it was years ago,especially over short distances. There are few things we could think about before booking a flight to make it cheaper.

When,where and how we have to book our flights? Many experts have done researches as Reak Seaney who says that "airlines know a lot about our buying habits" therefore not everything that is said in internet is true. What I have noticed from my experience and is almost always working:

• Book as early as possible - well,don't do it an year ago because promotions show up on airlines' websites around 3-4 months before the flight. It is said that there is an eight-week rule,which means that booking 8 weeks earlier guarantees us the best price.As a mathematician I'm inclined to believe it as there is a formula created by two scientists that proves it.
• Find out which are the lowcost airline companies that fly in your region and frequently check their websites for offers to different destinations.
• Study when is the low season of the place you'd like to visit and try to go then. Flights woulsd be definitely cheaper as well as hotels too.
• Make an experiment - check one destination for a week or two and see which time of the week you'll get lower price.I've heard about Tuesday afternoon but of course it is not a rule.Although it is true that booking on Wednesday is cheaper that booking on Friday. My experience says: weekdays evenings.
• You will notice that flights on Saturday and in the middle of the week are usually cheaper. So when you plan a trip first book the flight and after that arrange your accomodation.
• If you book a lowcost flight try to travel only with hand luggage because for other luggage you have to pay extra. Most airlines allow between 8 kg and 15 kg for the baggage on board (usually 10kg). There are many tricks to collect all your stuff in the suitcase - here is my favorite one. Put on your heaviest and most voluminous clothes when traveling and you can easily collect a 2 week luggage in one little bag.
• Besides adding a luggage to your ticket lowcost airlines also offer priority boarding(not needed at all);insurance;car rentals;hotel bookings,etc. Just don't take advantage of that offers, you can find them much more cheaper if needed in other websites or/and agencies. 

I hope that information would work for you too. Actually there is another thing I practice sometimes - I choose a destination according to the cheapest flight I find. As still there are many places over the World I want to visit, I have a huge choice.

If you know some other tricks for better prices I'll be glad to read them in the comments.
