Taxes are a combination of Government taxes and airline charges which combine together to give you your total taxes. Generally, the more stops you make the more tax you will have to pay, as every time you land and take off again taxes will be charged. Some airlines charge more for taxes than others, so it is our job to ensure that we chose the correct airlines for your flights so that we can keep the cost as low as possible for you. Unfortunately, part of the tax is levied against the price of fuel which is dependent on the price of oil. This can fluctuate regularly, and it nearly always increases. You will pay the taxes as quoted on the day of your final payment; it is therefore an advantage to pay for the ticket as early as you can.
