The United Kingdom has the world’s highest taxes for airline passengers, known as the Air Passenger Duty (APD). In this post, I wanted 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 has made changes to the APD as of April 2023, so I wanted to go over what those changes mean for passengers.What is the UK Air Passenger Duty?How much is the UK Air Passenger Duty?When does the UK Air Passenger Duty apply?When do you pay the UK Air Passenger Duty?What’s the difference between the UK APD & fuel surcharges?Are there any ways to minimize the UK APD?Plan your stopover strategicallyMix economy & business classFly out of InvernessPosition yourself to another countryBottom lineWhat is the UK Air Passenger Duty?The UK’s Air Passenger Duty is a steep tax levied on any flight originating in the UK — this means that if you’re simply transiting the UK between other countries on one ticket then you shouldn’t be on the hook for this. Rather it’s charged based on having a journey originating in the UK (even if it’s the return portion of a ticket), regardless of where you’re connecting.Suffice to say that the UK APD is controversial:It’s a tax against those traveling from the United Kingdom, rather than those who simply connect in the United Kingdom, as the latter group doesn’t have to pay thisHigh taxes negatively impact demand for air travel, since it makes flying more expensive; airlines serving the UK have long fought against this tax, since it raises the cost of airline ticketsFor some historical context, the UK APD was first introduced in 1994 and was intended to raise money for the government. When it was first introduced the tax was £5 for destinations within Europe, and £10 for destinations outside of Europe (as you’ll see below, it has gone way up).Over the years the tax has almost been viewed as an environmental tax, intended to encourage other forms of transportation. Then again, those are pretty limited if you’re traveling long haul from the UK. From an environmental standpoint, there are two issues with this:It does nothing to encourage airlines to invest in more efficient aircraft, since you’d think that would be a consideration in terms of emissionsIf this is about the environment, you’d think transit passengers would be on the hook for this, since they have an even bigger environmental impact when taking two flightsThe UK has the world’s highest aviation taxesHow much is the UK Air Passenger Duty?The UK Air Passenger Duty amount is broken down based on the distance you’re flying, and the class of service you’re flying in. There are four different pricing bands, and here’s the pricing as of April 1, 2023:For domestic flights (only within England, Scotland, Wales, and Northern Ireland), the APD is £6.50 (~$8) in economy, and £13 (~$16) in a premium cabinFor international flights of up to 2,000 miles (short haul), the APD is £13 (~$16) in economy, and £26 (~$32) in a premium cabinFor international flights of 2,001 to 5,500 miles (long haul), the APD is £87 (~$107) in economy, and £191 (~$236) in a premium cabinFor international flights of more than 5,500 miles (ultra long haul), the APD is £91 (~$112) in economy, and £200 (~$247) in a premium cabinIn addition to seeing some adjustments to the APD amounts, another major change as of April 2023 is that we’ve seen the introduction of a new domestic pricing band, as well as the introduction of a new ultra long haul pricing band.Now, there are some further details to be aware of:For these purposes, a premium cabin would include anything other than economy, so it includes premium economy, business class, and first classIf you upgrade your seat the higher UK APD applies, which is why many airlines will request a co-pay when upgrading a flight out of the UK (to account for this cost)The distance isn’t measured between your origin and destination, but rather between London and the capital city of the country you’re traveling toThe distance isn’t measured by the distance of your nonstop flight from the UK, but rather by your final destination on your itinerary (assuming continuous travel with no stopovers of more than 24 hours); in other words, the same APD applies whether you fly from London to New York nonstop, or from London to Paris to New York, even though the former itinerary has a much longer nonstop flight out of LondonThe UK APD is in addition to any airport taxes and fees, so this isn’t even all you’ll pay in taxes and fees when originating in the UKThe UK APD could total ~$247 one-wayWhen does the UK Air Passenger Duty apply?Understandably there’s confusion about under what circumstances the UK Air Passenger Duty applies, so let me try to break it down as simply as possible:The UK APD applies based on whether you have a flight itinerary originating in the UK; an itinerary is considered to be originating in the UK if you’re on the ground there for more than 24 hoursThe UK APD doesn’t apply for any flights to the UK, as it’s purely a departure taxThe UK APD doesn’t apply to people who are simply connecting in the UK for under 24 hours on a single ticketThe UK APD doesn’t apply to children under the age of 16Let me give some examples, and with each, I’ll explain whether or not the UK APD applies:Are you flying from London to Los Angeles? You’ll have to pay the long haul APDAre you flying from Los Angeles to London? You won’t have to pay the APDAre you flying from New York to London to Paris, and are connecting in London for under 24 hours? You won’t have to pay the APDAre you flying from Dubai to London to New York, and are connecting in London for under 24 hours? You won’t have to pay the APDAre you flying from London to Amsterdam to Los Angeles, with a connection of under 24 hours in Amsterdam? You’ll pay the long haul APDAre you flying from London to Amsterdam to Los Angeles, with a connection of over 24 hours in Amsterdam? You’ll pay the short haul APDHopefully, that covers most scenarios. As you can see, the APD is calculated based on the final destination of your ticket departing the UK, with continuous travel within 24 hours.The UK APD doesn’t apply when traveling to the UKWhen do you pay the UK Air Passenger Duty?The UK Air Passenger Duty is collected by airlines directly at the time of booking. So when you book a ticket that’s subjected to the APD, you can expect that your ticket price will include the APD. This isn’t something you have to pay at the airport, or after the fact, for example.The UK APD is added to your ticket costWhat’s the difference between the UK APD & fuel surcharges?There’s often confusion about the distinction between the UK Air Passenger Duty and fuel surcharges, given that UK airlines are known for charging both, and it’s also why award tickets originating in the UK can cost so much. Just to clear that up:The UK APD is a government-imposed fee that can cost up to £180 on a one-way flightFuel surcharges are imposed directly by airlines, and are a junk fee that has nothing to do with the governmentWhile only some airlines add fuel surcharges (like British Airways), all airlines have to charge their passengers originating in the UK the Air Passenger Duty. Just to give an example of that, say you’re redeeming American AAdvantage miles for business class travel between London and New York.If you book for travel on American, there are no fuel surcharges, and you’d pay a total of $322.15, which accounts for the UK APD, as well as all the airport taxes and fees (which are on top of the UK APD). Meanwhile, if you were to book British Airways instead, there would be fuel surcharges, and you’d pay $682.95. As you can see, in this case, the fuel surcharges are $360.80.Comparing AA & BA award flight costsSince this often creates confusion, let’s look at flights in the other direction, from New York to London. If you were to book American, you’d pay just $5.60 in taxes and fees (there are no fuel surcharges or UK APD). Meanwhile, if you booked British Airways, you’d pay $731.20, meaning that the fuel surcharges are $725.60. Yes, fuel surcharges are higher originating in the US than the UK, but there’s still no UK APD here.Comparing AA & BA award flight costsHopefully, that clears up any confusion regarding the distinction between the UK APD and fuel surcharges.Flights may be subjected to the UK APD and high fuel surchargesAre there any ways to minimize the UK APD?There’s no real way to “beat” the UK Air Passenger Duty, though there are some ways to minimize it, or at least be strategic about it. Different people will have different takes on the extent to which these strategies are worth it, but I figure they’re at least worth pointing out. Let me give a few examples.Plan your stopover strategicallyFor example, say you’re redeeming British Airways Avios to fly roundtrip from New York to Paris via London, and you plan to have a stopover of more than 24 hours in London in one direction. If you’re going to do that, I’d highly recommend having your stopover in London on the outbound, rather than the return. Why? Because you’d only pay the short haul APD (£26), rather than the long haul APD (£191).At the point in your itinerary where you’ve been in London for over 24 hours, you’ll be embarking on an itinerary of under 2,000 miles (to Paris), rather than an itinerary of over 2,000 miles (to New York).Furthermore, if you want to visit London but only briefly, try to plan a stopover of just under 24 hours. That way you can avoid paying the UK APD altogether, all while still visiting the UK for a bit.Mix economy & business classWhen booking award tickets, some people like to travel one direction in business class and one direction in economy class, to splurge without redeeming too many miles. If you’re traveling to & from the UK and are using this strategy, ideally fly business class on your flight to the UK, and economy on your flight from the UK.For one direction of travel, this would lower your APD from £191 to £87.Fly out of InvernessWhile Inverness is part of the United Kingdom, the Scottish Highlands and Islands are exempt from the UK APD. This is part of an agreement that dates back all the way to 1994, so it’s a nice little loophole. The catch is that not many people would naturally be starting there, and Inverness has fairly limited service.For example, if you fly from Inverness to London to New York using American AAdvantage miles in business class, you’d pay $458.75, the vast majority of which is carrier imposed surcharges, as there’s no APD.UK APD example out of InvernessMeanwhile if you took just that same flight from London to New York, without originating in Inverness, you’d pay $682.95, which is due to being charged the UK APD.UK APD example out of LondonPosition yourself to another countryYou can avoid the UK APD by flying out of a country other than the UK, and that could potentially save you quite a bit, especially on a business class ticket. There are a few ways to go about this:Some people will position themselves to Dublin to start their itinerary, because flights from Ireland aren’t subjected to the UK APD (and as a bonus, flights out of Ireland are often cheaper than flights out of the UK, even taking that out of the equation); in some cases flights between the UK and Ireland can cost under $20, so this could save you some significant moneySome frequent flyer programs allow stopovers, so you can use those strategically; for example, Air Canada Aeroplan allows stopovers for 5,000 points one-way, so you could fly from London to Copenhagen to New York with a stopover of just over 24 hours in Copenhagen, and then you’d only have to pay the short haul APD rather than the long haul APDAvoid the UK APD by traveling from IrelandBottom lineThe UK Air Passenger Duty is the world’s highest tax that’s levied on airline passengers. This applies to passengers with itineraries originating in the United Kingdom, and the tax ranges from £13 for an international short haul economy flight, to £200 for an international premium cabin long haul flight.Hopefully the above provides a useful summary of how this works, and if anyone has any questions, please let me know. While the UK APD can’t be avoided altogether, there are most definitely ways to minimize it.What has your experience been with the UK APD?
