How to use ITA Matrix to find cheap British Airways flights from Europe

A comment on HFP earlier in the week about ‘how do I use Matrix?’ made me realise that it is a while since I talked about the ITA Matrix online tool.  This allows you to very quickly discover how you can save money – a lot of money – on British Airways Club World (or any other airline) tickets by starting outside the UK.

With British Airways, Dublin and Germany often provide good pickings.  With Qatar Airways, good deals often involve starting in Scandinavia.  ITA Matrix can crawl various starting points in one search.

Using ITA Matrix

The key to finding cheap ex-Europe long-haul flights is a nifty bit of software called ITA Matrix, which is now owned by Google.

Once you’ve got your head around ITA Matrix, you can very quickly do your own fare searches and find your own deals.

When you go to the ITA Matrix home page, you will see what looks like a more complex version of Expedia etc.  Unfortunately, it likes to work in code and not in plain English!  This is how you get it to work.

Under ‘From:’, cut and paste:



(Delete the gap between LIN and LIS when you cut and paste)

This is a list of major European airports by airport or city code.  I’ve added some smaller Qatar Airways favourites such as Pisa, Bucharest and Sofia.  Some of these starting points are a long way from London, so you will need to sort the results to find somewhere you would be happy travelling to in order to start your trip.

For a Qatar Airways search, replace BA+ with QR+.

Under ‘Destination:’, enter:

[the airport or city code you want, eg NYC for New York] :: BA+

eg NYC :: BA+

Under ‘Dates:’, enter rough dates that suit you.

Under ‘Sales city:’ enter LON.

This is important, it ensures pricing is in £ and that you are only shown tickets that are bookable by a UK resident.

Make sure ‘Allow airport changes’ is ticked so that you see connection flights into Gatwick and City as well when searching for BA.

Under ‘Cabin’, select the cabin you want – let’s assume ‘Business’. 

Under ‘Only show flights with available seats’, decide whether to tick or not. 

If you MUST travel on a certain date, tick it.  If not, leave it unticked as you will get an idea of prices even if they are not available that day.

You’re done!  Click ‘Search’.

When you get your results, re-order by price as it does not happen automatically all the time.

An example

Let’s try to find a good New York fare.

Under ‘From:’ I use the first line of code above:  



(Delete any gap between LIS and MAD when you cut and paste)

Under ‘Destination:’ I use NYC :: BA+

Under dates I use 3 July to 12 July (note that a 7-day minimum stay applies to a lot of very cheap fares).

Under ‘Cabin’ I select Business.

Under ‘Sales city’ I type LON

Under ‘Show available seats’ I tick, assuming I must travel that day

And this is what you get from ITA Matrix:

How to use ITA Matrix

As I would have guessed, a Dublin fare is at the top at £1,305.  Only a little more expensive is an option from Warsaw which may be of interest if you wanted to wrap a short break around your US trip.

Note that you cannot stopover in London for more than 24 hours for free – it would trigger Air Passenger Duty.  You could, for example, go to Dublin for the weekend, fly back to London for 5pm Sunday on the first part of the ticket and head back to the airport for a 4pm departure to New York on Monday.

Because we left ‘Show bookable seats’ ticked, it SHOULD be possible to book these seats via or even Expedia.  It is a case of trying to get the exact same flights to show up.  At worst, if you ring BA and give them the exact flights that come up, they should be able to pull up the same price.

Fare rules

One upside of these fares is that cancellation, stopover and change policies are often more generous than they are from the UK.

ITA Matrix can show you the full fare rules if you click on a price (eg £1,305) and then on the underlined ‘rules’ word under ‘How to buy this ticket’.

For the £1,305 Dublin to New York fare, for example, you will see that:

you can stopover in London for €150 – but it would trigger Air Passenger Duty as well

the ticket can be changed for €300 plus any fare difference

it cannot be refunded

This is obviously a very brief overview to a very complex issue.  I also do not claim to be an expert on this.  I haven’t considered, for example, which cities earn higher European tier points.  Start in Athens for example and you get 80 tier points instead of 40 tier points for the short-haul sectors.  This could be worth paying a little more for if you are chasing status.

And you must remember that you MUST take the first flight.  You CANNOT get on the long-haul plane at Heathrow.  Your ticket will have been cancelled as soon as you were a no-show for the European flight.

Coming back, you have to fly the last leg unless you have hand baggage as there is no guarantee that BA will tag your case just to London.  One way around this is, if possible, to have your final flight leaving from Gatwick or City – BA is then forced to tag your bag just to Heathrow.

Legally BA is entitled to pursue you for the fare difference but is unlikely to do so.  It may (and occasionally does) pursue a travel agent who books such a ticket for you – the agent is legally liable as they make the contract with BA – so if you plan to skip a final leg then make sure you make your own booking and do not involve a third party.

  1. Charlie says:

    In light of the current avios redemption downgrade concerns, is ITA Matrix useful to check if a cabin is oversold?

    I’m travelling next week on a redemption ticket, and so I attempt to price up 9 seats in my cabin (the maximum allowed), on same flight.

    The results show 9 tickets for sale so can I assume there are seats available? And less chance of a downgrade?

    • Charlie says:

      I tried doing this for LHR to HKG today in business class (which I know tends to be busy), with an increment from 1 to 9 seats, and I can see flight availability decreasing. So it does look like it can show availability this way.

      • There is a thread in the BA forum on flyertalk for checking loads. You can post in there the details of the flight and someone will check in expertflyer and give you the availability across all selling classes. That will probably give a bit better picture.

  2. TBH I find Google Flights a much easier tool, and I can build departure/arrival times to suit my needs, and at the bottom just click on the airline and it takes you straight there with everything already filled in

    • You’re limited to how many airports you can search from with Google flights.

      • Yes there are advantages and disadvantages, I think the advantages out way the other

        • Agreed, it’s just a shame that Google appear to have shifted processing power from Matrix across to Flights – at least they haven’t closed the former down though (for now at least!)

  3. Wally1976 says:

    Just remembered someone posted this link in the past for booking itineraries on ITA Matrix. No idea if it’s any good or not!

  4. Oliver East says:

    Is it possible to search for flights going business outbound and premium economy on the return leg?

  5. Is there an option to search flights according to tier points? Essentially to find the cheapest tier point.

    • No, Matrix doesn’t know anything about BA TPs – you just need to be aware of that yourself 🙂

    • PS the FT TP-run thread will give you some good ideas if looking to do a run…
