Maximise your Avios, air miles and hotel points

How Santiago shows up the oddities of Avios reward pricing – with taxes from £59 to £625

Links on Head for Points may support the site by paying a commission.  See here for all partner links.

Avios reward pricing is all over the place. It is complex enough when just looking at British Airways flights and the various combinations of cash and points, but when you factor in Iberia and partner airlines it gets even crazier.

I thought that Santiago in Chile was a good example because it is served by British Airways, Iberia and LATAM. I’ve not looked at options with Qatar Airways because it is a bit of a diversion to go via Doha given the alternatives.

Even if you DON’T want to go to Chile, keep reading because the same principles apply to other Iberia routes.

Avios flights to Chile Santiago

Option 1:  Fly British Airways direct from London to Santiago

Santiago is better value than it should be, sitting in Zone 8 of the (unpublished) British Airways reward chart. The flight is 7,228 miles and it should technically be in Zone 9 and priced the same as Sydney! 

I have selected the ‘most Avios, least cash’ option as this is clearly the best for someone using a British Airways American Express 2-4-1 voucher.

For a return flight in Club World / business class you will need, for one person:

  • 220,000 Avios + £625 off-peak
  • 240,000 Avios + £625 peak

Due to a ba.com bug you will currently see a lower taxes figure of around £580. The correct figure, using Reward Flight Saver, should be £625.

Option 2:  Fly Iberia direct from Madrid to Santiago, booked on ba.com or iberia.com

Even though you should book this flight on ba.com, to make cancellation easier if necessary, it still prices off the Iberia Avios reward chart because it is an Iberia flight.  Santiago is in Zone 7 of the Iberia Avios reward chart.  Iberia is also being generous here, because the flight is 6,649 miles and it should technically be in Zone 8.

You pay (again, I take the ‘most Avios’ version which is best for someone using an Amex 2-4-1 voucher):

  • 102,000 Avios + £190 off-peak (see screenshot below)
  • 150,000 Avios + £190 peak

You also need to add in the cost of getting to/from Madrid on a separate ticket.  You make substantial savings (£253) on Air Passenger Duty by taking a separate economy flight to Spain. Because Santiago is over 5,500 miles it falls into the highest UK APD band.

The total savings, as you can see, are ludicrous when flying on Iberia.

TWO people could fly Business Class, from Madrid to Santiago, using a British Airways American Express companion voucher for just 102,000 Avios + £380 return off-peak.

Option 3:  Fly LATAM direct from Madrid to Santiago, booked on ba.com

Finally, here is an option with a partner airline.  LATAM is no longer a member of the oneworld alliance but retains codeshare and frequent flyer partnerships with British Airways and Iberia.

This is what you pay to fly with LATAM.  Remember that, as a partner airline, all dates are priced as peak dates:

  • 278,500 Avios + £59.70

You also need to add in the cost of getting to/from Madrid on a separate ticket.

If the Avios cost looks high, it is because there was a huge LATAM devaluation last year.

I can’t show you a screenshot because, at the moment, LATAM redemptions between Madrid and Santiago are not bookable on ba.com. It is bookable at iberia.com, although business class reward seats are VERY hard to find.

Do not book this ticket on the Iberia website if you can help it because partner airline redemptions booked via Club Iberia Plus cannot be cancelled. Book via ba.com and you can cancel for a full refund for the usual £35 fee.

Which option is best?

As I said earlier, this article isn’t really about Santiago.  It is more about highlighting the huge differences in taxes and charges if you can fly with Iberia or a partner airline.

In this particular example, it is a no-brainer to take Iberia from Madrid. Whilst LATAM has lower taxes, the additional Avios required means that it is poor value overall. This is especially true if you have a British Airways American Express 2-4-1 companion voucher for Iberia.

British Airways is bad value on this route. However much you may prefer a direct flight from London, the lure (assuming two travellers with a 2-4-1 voucher) of paying 102,000 Avios + £380 between you from Madrid vs 220,000 Avios + £1,250 from London is probably too strong to resist.

In fact, the Iberia option is so cheap that I’d be tempted to keep my 2-4-1 voucher for another day and pay the full price for two people of 204,000 Avios + £380 ….

In a sister article to this, coming soon, we’ll show you how you can save on redemptions on some oneworld partners by booking them via Qatar Airways Privilege Club or Finnair Plus instead of British Airways Club.

  • FCP says:

    Can you return to UK on same ticket / for same mileage?
    Ie get a one way ticket to Madrid and then a ticket MAD-SCL-MAD-UK to allow through check on return?
    Presumably only bootable by phone?

    • Scotsman says:

      Yes you can, but as you said you’ll need to call. The inbound leg can be done fully online if 2 flight and single booking and will have 2 booking refs.

      • Nico says:

        Yes very common practice, also you can do MAD-LHR in economy to save avios

        • jek says:

          Flying back in Economy is not necessarily saving a lot of money. For us it was just 6000 Avios saved.

        • Londonsteve says:

          Does anyone know if after arriving in MAD on a long haul service in Business you can access the lounge if your onward connecting flight to London is in Economy, assuming the whole flight is booked as a reward seat with Avios in a single booking?

    • Dave Hughes says:

      I tried this from Doha and when I added mad-man on the return leg in economy the taxes jumped to £1000+ , I questioned it twice and In the end gave up and booked a £28 cash ticket and went hand luggage only and chanced the connection of 2 hours ….

      • 1958 says:

        I had the same issue booking EZE – MAD – LHR on Avios.
        I questioned the increase, and the booking was made (provisionally), then sent to “Ticketing”. Got a much cheaper price when Ticketing completed their review.

        • Tripio says:

          I’m thinking about doing the same but haven’t priced it yet. How much more does the MAD-LHR add to the EZE-MAD itinerary?

          • jek says:

            You can check it by pricing EZE-LHR via MAD and compare it to EZE-MAD. It’s basically the difference. You probably want to make sure to fly IB on MAD-LHR, otherwise it will get much more expensive.

  • JaneDoe says:

    Need some help pls as looking to do my first reward booking for Iberia flights.
    Costa Rica – London in Club for Easter Monday next year
    For the least Avios and cash should we book 2 separate tickets SJO- MAD & MAD – LHR?
    What is the difference in cancellation policy if we book on Iberia website vs BA?
    Am I right in thinking that Iberia releases flights a few days before BA?
    Appreciate all advice. Thanks.

  • Dawn says:

    Excellent article. We struggle to earn Avios being pensioners with no business spend so this ability to book using our 2-4-1 and less Avios is really important to us. Looking forward to future articles booking via Finnair/Qatar as they’re our preferred airlines.

  • SimonCH says:

    I reported this last year on both the Gold and Exec Club pages on Facebook when we got redemption tickets to Santiago, booked via BA with an Amex 241 voucher also. We paid 102,000 and £391.60 in taxes ( variation could be due to exchange rates at the time ).

    The flights was excellent, better than BA on a new A350 with closed suites.
    Yes, it was better than the 350 BA service we usually do to Las Vegas and Phoenix every year. Food, drinks, snacks, etc.
    The lounge at Madrid was also great and allowed Pre Flight table service dinner, since we took the 23.59hrs flight.

    Highly recommend this route for the cost.
    Also Santiago is a wonderful city.

  • Novice says:

    This is great to know but whenever I look I can never find available flights. Am I doing something wrong?

    • JDB says:

      I fear so, it’s not difficult finding Iberia availability, even long after T-360.

    • Rob says:

      Loads of Iberia availability. LATAM is very hard.

    • Lumma says:

      Bogotá and Mexico City are the easiest iberia routes to find seats on, as they’ve 3 flights each day. Only 85k avios return off peak too

    • Michelle Chesterton says:

      I also struggle to find Business availability through the Iberia app, even though they are showing in the BA app. Iberia only seems to show me Economy.

  • Paul says:

    I do wonder if advertising what many already know, won’t lead to the closure of such “loopholes”

    • Richie says:

      Has been around for a long time and has not been closed, probably not a “loophole” and just an “oddity”.

      • CJD says:

        It’s not a loophole, there will be far more Avios in circulation in BA accounts which is why BA redemptions cost far more.

  • Callie Foster says:

    I thought being Uk based, I could only use a companion voucher for flights starting in UK?

  • Antony says:

    This is exactly what I have booked for 2026. Originally booked with BA and realised how much cheaper it was with Iberia – taxes and Avios. Luckily managed to cancel BA within 24hrs. And the BA flight was the old style seating so feels even better!
