Just to give you an idea of the taxi fares from the Malta International Airport to the main cities and villages:
The above fares are not inclusive of administrative fees. Furthermore, on Christmas day and the 1st of January an additional fee of 4.50 euro is charged.
Cheaper is the option of catching a bus. As soon as you exit the airport, you will find a bus stand with different buses. The bus fare is € 2.00 in summer and € 1.50 in winter. Be sure to have exact change as you might be left out from the driver. The following routes are available: X1 Cirkewwa, X2 San Giljan, X3 Bugibba, X4 Birzebbugia, 117 Mater Dei-L-Imqabba, 119 Marsaskala, 135 Marsaskala-Mater Dei, 201 Rabat.
At the airport there is a Tallinja information desk, where you can buy a bus card that will allow to pay cheaper fares. If you want to know more visit the public transport website by clicking here.
You can also decide to rent a car upon arrival, depending on the time of arrival of course. You can always decide to book your car beforehand, by visiting the MaltaAirport website. Please remember that in Malta you will need to drive on the left hand side, as it is in the UK.
There are other possibilities: you can book a private cab with other companies, in many cases this will be cheaper than a white taxi. My favourite cab company is Ecabs.
Uber is not available in Malta, but you will find Taxify, just download the app and book your cab with a click!
There is also an Airport shuttle service operated by MaltaTransfer.
