Opodo (www.opodo.co.uk) is one of the many online travel agents that allows you to purchase Air Malta flights (whether departing from Malta or anywhere else).
Should you buy an Air Malta flight with them, simply enter MSEOP15 in the promo code box, and you will get £15 off flights over £250. The code expires on Wednesday 16 January, but you can travel at any time.
Opodo offers some good value prices, but before you book it’s probably worth double-checking on the airmalta.com website to confirm that you can’t get the flight cheaper with Air Malta directly (don’t forget to take the £15 discount for the Opodo booking into account).
This code also works for Lufthansa and Easyjet (and indeed any other airline you can book through Opodo), but if you’re thinking of using it for a Lufthansa flight from Malta, you’re probably better off using this €20 off code.
