Book Iberia to Avoid BA Surcharges

British Airways reward flights carry enormous surcharges. This guide shows UK travellers how to use Iberia, Aer Lingus and other partners to slash the cash cost of Avios redemptions — sometimes by hundreds of pounds.

Last updated: September 2026 10 min read

If you have ever been shocked by the “taxes and fees” line on a BA Avios booking, you are not alone. The good news is that you can often fly the same route in the same cabin for a fraction of the cash cost — by booking through a partner airline and, in many cases, departing from a different city. This guide walks through every option, starting with the most popular: Iberia.

What you’ll learn:

  • Why BA surcharges are so high in 2026
  • How to book Iberia reward flights step by step
  • The Aer Lingus transatlantic alternative
  • Other low-fee partners (AA, Qatar, JAL)
  • When BA Reward Flight Saver is worth it
  • The positioning-flight playbook

1. The surcharge problem with BA reward flights

You have found the perfect reward seat, the Avios are ready to go — and then you see the “taxes, fees and carrier charges” line. On a return Club World booking from London, British Airways can ask for £400 to £500 or more on top of your Avios. A large slice of that is BA’s own carrier-imposed surcharge, a legacy of what used to be called the fuel surcharge. On 27 May 2026 BA increased these surcharges again, making the cash portion of long-haul premium awards heavier than ever.

On top of that, every passenger departing the UK on a long-haul flight pays Air Passenger Duty (APD). From 1 April 2026 the rates are £102 per person in economy and £244 in premium cabins (business and first) for Band B destinations (up to 5,500 miles), rising to £106 and £253 for Band C (over 5,500 miles). APD applies on reward flights exactly as it does on paid tickets.

The good news: you do not have to accept these costs. Because Avios transfers freely between British Airways, Iberia and Aer Lingus at a 1:1 ratio, you can book the same type of flight for a fraction of the cash by choosing a different operating airline and sometimes a different departure city.

2. Why Iberia is the go-to alternative

Iberia does not levy the same aggressive carrier-imposed surcharges as British Airways. A business-class reward from Madrid to the US can cost a fraction of the fees you would pay on a BA metal flight from London. And because both airlines use Avios, the points cost is broadly comparable — often identical on routes that fall in the same distance band.

Combine that with the fact that a cheap positioning flight from the UK to Madrid (Ryanair and Vueling both serve this route heavily) lets you start your long-haul journey from Spain, and you sidestep both the BA surcharge and the punishing UK Air Passenger Duty in one move. For a couple flying Club World return, that can represent a saving of well over £500 compared with the same trip on BA from Heathrow.

Route (return, business class)BA from LondonIberia from Madrid
To New York~£499 in taxes & fees~£150–£200 in taxes & fees
To Buenos Aires~£550+ in taxes & fees~£170–£230 in taxes & fees
To Bogotá~£480+ in taxes & fees~£140–£190 in taxes & fees

Figures are indicative and based on September 2026 searches. Actual amounts fluctuate with route, date and currency. Always confirm the cash total at the point of booking.

3. How to book Iberia reward flights step by step

1

Create an Iberia Plus account

If you do not already have one, sign up at iberia.com. The account must be at least 90 days old before you can transfer Avios into it, so set one up now even if you are not ready to book yet.

2

Transfer your Avios

Move Avios from your BA Executive Club account (or Aer Lingus AerClub) into Iberia Plus via the "Combine my Avios" feature on avios.com. Transfers are 1:1 and usually instant, though they can occasionally take 24 hours. Make sure your name and details match exactly across both accounts.

3

Search for availability

Search on iberia.com using your Iberia Plus login and select "Use Avios". You can also search on ba.com which often shows Iberia-operated flights — but compare the cash fees on both sites, as BA sometimes adds higher charges for partner bookings.

4

Book the flight

If not using a BA companion voucher, book directly on iberia.com for the lowest fees. If you are using a companion voucher, you must book on ba.com — the voucher is valid on Iberia-operated flights booked through BA.

5

Add a positioning flight

Book a separate cheap flight from the UK to Madrid (or whichever Iberia hub you are departing from). This is not part of your Avios booking — it is a standalone cash ticket, usually under £50 on a low-cost carrier.

The 90-day trap. The most common mistake is forgetting to open the Iberia Plus account early enough. If your account is under 90 days old when you try to transfer Avios, the system will block the move. Create the account today — it costs nothing.

Earn Avios faster — and use a companion voucher on Iberia flights

The BA Amex companion voucher works on Iberia-operated flights when booked through ba.com, halving the Avios cost on top of the lower surcharges. It is the single best way to fly Iberia business class for less.

4. Aer Lingus: the other low-surcharge route

Aer Lingus operates a growing transatlantic network from Dublin and Shannon, and its reward flights come with considerably lower surcharges than BA. Departing from Ireland also means no UK Air Passenger Duty. For UK-based travellers, a Ryanair or Aer Lingus hop to Dublin, followed by an Avios business-class reward across the Atlantic, is a tried-and-tested formula.

Avios transfer 1:1 into AerClub (Aer Lingus’s loyalty programme) just as they do into Iberia Plus, and there is no 90-day waiting period — transfers are available immediately. Off-peak business class from Dublin to the US East Coast starts at 50,000 Avios each way; West Coast at 62,500 Avios.

Extend beyond Dublin for just 4,000 Avios

Aer Lingus allows you to add a connecting European flight to your transatlantic reward for a small Avios supplement, effectively making Dublin a gateway to the rest of Europe on your return.

5. Other low-surcharge partners worth knowing

Iberia and Aer Lingus are the headline acts, but they are not the only way to dodge surcharges. Several oneworld partners carry minimal fees when booked with Avios:

AirlineBest forTypical fees
American AirlinesUS domestic flightsMinimal — often just $5.60 per sector in security fees
Qatar AirwaysMiddle East, Asia, AustralasiaModerate — much lower than BA on comparable routes
Japan Airlines (JAL)Japan domestic & intra-AsiaVery low taxes on Japanese domestic sectors
Cathay PacificAsia & long-haul from Hong KongModerate — significantly less than BA long-haul
Alaska AirlinesUS West Coast domesticMinimal — similar to American Airlines

Some countries (including Japan, Australia and Brazil) restrict or prohibit fuel surcharges on flights departing their territory, so bookings originating from those regions often carry especially low fees regardless of the airline.

6. When staying on BA makes sense: Reward Flight Saver

British Airways does offer a partial answer to its own surcharge problem. The Reward Flight Saver (RFS) option lets you pay more Avios in exchange for a capped, predictable cash fee. On short-haul European flights the cash portion can drop to as low as £1, making RFS superb value within Europe.

On long-haul routes, RFS still trades Avios for a lower cash bill, but the trade-off is steeper — you are paying significantly more Avios to reduce the cash outlay. Whether that is a good deal depends on how you value your Avios. RFS is available in economy, premium economy and business class but not First Class, and requires you to have earned at least one Avios in the past 12 months.

RFS only applies to BA-operated flights. It does not cover partner airlines or franchise services, and every segment of your booking must be eligible. If one leg is not, RFS pricing disappears for the whole journey.

Keep the cash savings — and cut the Avios cost too

A companion voucher halves the Avios cost of a reward flight. Stack that on top of Iberia's low surcharges and you have the cheapest way to fly business class on points from the UK.

7. The positioning-flight playbook

A “positioning flight” is a separate, cheap ticket you buy to get yourself to the departure city of your Avios reward. It is not part of the reward booking — just a standalone fare on a low-cost carrier. The saving on surcharges and APD almost always dwarfs the cost of the positioning leg.

  • London to Madrid. Ryanair, Vueling and easyJet all serve this route heavily. Fares start from £15–£30 each way if booked early. Madrid Barajas is Iberia’s main hub with long-haul departures to the Americas.
  • London to Dublin. Ryanair, Aer Lingus and others fly multiple times daily. Dublin is your gateway to low-surcharge Aer Lingus transatlantic rewards.
  • London to Amsterdam or Paris. Useful for KLM or Air France rewards booked with Flying Blue (Amex Membership Rewards transfers). Not Avios, but worth knowing as a broader surcharge-avoidance strategy.

Build in a buffer. Book your positioning flight to arrive the day before your long-haul reward departs. If the positioning flight is delayed or cancelled, your Avios ticket is a separate booking and the airline has no obligation to wait for you.

8. Mistakes to avoid

Accepting BA’s surcharges as inevitable without comparing Iberia or Aer Lingus fees first.
Forgetting to open an Iberia Plus account 90 days before you need to transfer Avios.
Booking an Iberia flight on ba.com without checking if iberia.com shows lower fees.
Cutting it fine with positioning flights — always arrive the day before your reward departs.
Using a companion voucher on iberia.com (it only works when booked through ba.com).
Ignoring partners like AA, Qatar or JAL that carry even lower fees on certain routes.
