Watch out for hot specials from the airlines straight after the Christmas period. Many airlines globally release specials - but you have to be quick.
If you want to be an astute traveller, then also keep your eye on those airlines who offer regular budget flights.
In Australia, travellers should look out for the new Tiger Airways which offers incredibly cheap flights between major cities - as long as you go through Melbourne.
In Europe, airlines like RyanAir, EasyJet, Air Berlin and Wizz Air offer stunning value.
In the US, Southwest, Air Tran and JetBlue have some great priced tickets.

Then again, dont forget that for many short journeys its a lot cheaper and just as quick to take a city to city bus or train. By the time you drive to the airport, park your car, get through the long queues at the check in and wait for the flight it might be just as quick to go by bus.

If you are buying online, transfer money to family or friends or involved in any form of group or association that receives payments, you should give serious consideration to having a Paypal account.
The most important reason for using Paypal is security.When you use Paypal your credit card details remain private, only known to you and Paypal. This reason should be strong enough to open an Paypal account today.
Paypal is also a lot cheaper than using banks if you transfer money to friends and relatives, especially if they live in other countries. Paypal transfers are instant and the fees very low compared to banks.

If you dont have a Paypal account, I strongly recommend you open one. Here is a direct link to Paypal.
