Understanding The UK Air Passenger Duty (APD), An Expensive Aviation Tax

The United Kingdom has the world’s highest taxes for airline passengers, known as the Air Passenger Duty (APD). In this post, I’d like to look at how the APD works — what is it, how much does it cost, when does it apply, and are there any tricks to minimizing it? The UK adjusts the APD every April, so I like to make a post at that time covering all of the latest costs associated with this.
