International Consolidated Airlines Group S.A.,trading asInternational Airlines Group and usually shortened toIAG, is a British-Spanishmultinational airlineholding company with itsregistered office inMadrid, Spain, and itscorporate headquarters inLondon, England.[4] It was formed in January 2011 after a merger agreement betweenBritish Airways andIberia, theflag carriers of the United Kingdom and Spain respectively, when both became wholly owned subsidiaries of IAG. British Airways shareholders were given 55% of the shares in the new company.[5][6][7][8]
Since its creation, IAG has expanded its portfolio of operations and brands by purchasing other airlines –BMI (2011),Vueling (2012) andAer Lingus (2015). The group also ownsLEVEL and Avios, afrequent-flyer programme.
The company is listed on theLondon Stock Exchange and theMadrid Stock Exchange. It is a constituent of theFTSE 100 Index andIBEX 35 Index.

British Airways and Iberia signed a preliminary merger agreement in November 2009.[9][10][11] In April 2010, they signed a full merger agreement, with an intended completion date of late 2010, subject to securing the necessary regulatory approvals.[12][13] The merger between British Airways and Iberia was completed on 21 January 2011, and shares in the new holding company IAG began trading in London and Madrid on 24 January.[14][15][16]
On 6 October 2011, IAG createdIberia Express, a new low-cost airline to operate short- and medium-haul routes from IAG's Madrid hub and provide transfer feed onto Iberia's longhaul network.[17][18] Iberia Express began operations on 25 March 2012.[19][20]
On 4 November 2011, IAG agreed in principle to acquireBritish Midland International (BMI) fromLufthansa, in a deal which would increase IAG's share of slots at Heathrow airport from 45% to 54%.[21][22] On 22 December 2011, IAG agreed a binding deal with Lufthansa to acquire BMI for £172.5 million.[23] On 30 March 2012, the purchase was approved, subject to the condition that the combined group divest itself of 12 daily slots and lease two daily slots at Heathrow airport. The acquisition was completed on 20 April 2012, and the BMI fleet and routes were integrated into the British Airways schedule throughout 2012.[24]Slaughter and May advised IAG on the BMI acquisition.[25]

On 8 November 2012, IAG made a cash tender offer to buyVueling, a Spanish low-cost airline based in Barcelona. The offer was €7 per ordinary share of Vueling, with the total cost of acquisition anticipated to be €113m. It was funded from internal IAG resources. The reported total assets of Vueling as of 30 September 2012[update] were €805m and in the nine months to 30 September 2012 it had generated profits before tax of €59m. An increased offer of €9.25 was accepted by the Vueling board on 9 April 2013, and received majority shareholder approval on 23 April 2013. IAG took control of Vueling on 26 April 2013.[26][27]
In December 2012, IAG completed the merger of the cargo operations of British Airways, BMI and Iberia into a single business unit,IAG Cargo.[28][29]

In January 2015, IAG made a bid of €1.36 billion forAer Lingus. This was expected to be accepted after the rejection of two prior bids.[30] In May 2015, the Irish government agreed to sell its stake in Aer Lingus to IAG,[31] as did the Aer Lingus board in late January 2015.[32] The takeover became irreversible on 18 August 2015.[33]

In March 2017, it was announced that a new low cost longhaul airline namedLEVEL was to start operating fromBarcelona in June 2017.[34]
On 29 December 2017, it was announced that IAG bought major parts of defunct Austrian leisure airlineNiki including 15Airbus A321 aircraft and traffic rights inDüsseldorf,Munich,Vienna,Zürich andPalma de Mallorca.[35] It is planned to establish a new Austrian subsidiary ofVueling as a replacement for Niki.[35]
In April 2018, it was reported that IAG was considering a takeover ofNorwegian, a low-budget competitor to the group,[36] however, by early 2019, IAG had fully disposed of its stake in Norwegian.[37]
At the 2019Paris Air Show, IAG signed a letter of intent to purchase 200Boeing 737 MAX aircraft consisting of the 737 MAX 8 and 737 MAX 10 variants to be allocated to the group's various airlines[38] even though at the time of the signing the 737 MAXwas still grounded worldwide following the two fatal crashes likely caused by the design of the MCAS system.[39] Aviation analysts have questioned IAG's leadership in making such an order when the 737 MAX design is still being rectified. IAG CEOWillie Walsh, shrugged off the plane's uncertain future. "We're partnering with the Boeing brand", he said. "That's the brand that I'm doing business with. That's the brand that I’ve worked with for years. And it's a brand that I trust".[40]
Also at the 2019 Paris Air Show, IAG agreed to purchase 14Airbus A321XLR aircraft, 8 for delivery toIberia and 6 toAer Lingus, with options for a further 14 of the aircraft.[41]
On 19 May 2022, IAG finalised the purchase of 50 Boeing 737 MAX aircraft consisting of the 737 MAX 200 and 737 MAX 10 variants with 100 options to be allocated to the group's various airlines, which was originally announced at the 2019 Paris Air Show.[42]
On 9 May 2025, IAG ordered up to 76 aircraft from Airbus and Boeing, out of which 32 firm orders and 10 options for theBoeing 787-10 will be allocated toBritish Airways, and 21 firm orders and 13 options for theAirbus A330-900 will be allocated to Aer Lingus, Iberia andLEVEL. It also revealed the firming of options for 18 additional aircraft, including six Airbus A350-1000 aircraft and six Boeing 777-9 aircraft for British Airways, and six Airbus A350-900 aircraft for Iberia.[43]
On 1 August 2025, IAG confirmed that the Boeing 737 MAX order will be allocated toVueling to replace their olderAirbus A320ceo aircraft.[44]
In November 2019, IAG announced that it planned to acquireAir Europa from Globalia, for €1 billion. The deal, funded by external debt, and was expected to be completed in the second half of 2020, subject to regulatory approval.[45] On 20 January 2021, IAG announced that it had renegotiated its deal to acquire Air Europa (via Iberia) for €500 million as a result of theCOVID-19 pandemic. It also negotiated to delay payment to Globalia for 6 years. Completion of the deal was expected to take place in the second half of 2021 with the acquisition subject to approval by the European Commission.[46][47]
In September 2021, IAG announced that British Airways would terminate its major short- and medium-haul base operations atGatwick Airport with immediate effect resulting in the cancellation of more than 30 routes. This came after labour negotiations regarding the handover of these operations, most of which were still suspended due to the COVID-19 pandemic, to a newly formed budget subsidiary within IAG failed.[48] In August 2022, IAG converted a loan to Air Europa into a 20% shareholding.[49]
On February 23, 2023, IAG announced completion of a deal to purchase the remaining 80% of Air Europa for 400 million euros.[50]
The European Commission, in January 2024, opened an in-depth investigation into proposed acquisition of Air Europa by IAG. Some of the markets competition concerns were: 1) Spanish domestic routes, including those between peninsular Spain and the Balearic and Canary Islands; 2) Short haul routes between Madrid and some of the main EEA, plus routes between Madrid and Israel, Morocco, the UK and Switzerland; and 3) Long haul routes between Madrid and North and South America.[51] The deal was scrapped in August 2024.[52]
On 5 June 2025, influential proxy adviser ISS urged IAG investors to vote against a remuneration policy which includes a one-off share award for CEOLuis Gallego, at the group’s next annual general meeting on 18 June.[53]

In 2012, it was reported thatBritish Airways' profits had been wiped out byIberia's losses, and that the Spanish airline was in a fight for its survival.[85] By 2013, Iberia had lost a billion euros, requiring IAGCEOWillie Walsh to defend the IAG merger.[86] After further losses, IAG's balance sheet was in deep deficit as Iberia fought low-cost competition and a recession, and Walsh admitted that British Airways should perhaps have postponed the merger, saying, "If I'd known the Spanish economy was going to deteriorate to the scale that it did, we may have delayed the decision but ultimately I believe the merger is the right thing".[87]From 2014 onwards, Iberia returned to profitability, showing Walsh's predictions had been justified.[88]
In February 2021, IAG said that it has lost about €7 billion due to the COVID-19 pandemic in 2020, but it had €10.3 billion of liquid funds to get through the crisis.[89]
British Airways, Iberia, Aer Lingus, Vueling and LEVEL operate under their separate brand names.[94]

It was announced in July 2018, that Avios.com would close to British Airways Executive Club members, with all points automatically transferred to British Airways.[99] Qatar Airways, the largest shareholder of IAG, switched to Avios as its frequent flyer currency in March 2022.[100] Fellow oneworld alliance member Finnair also adopted Avios as its currency for Finnair Plus in March 2024.[101] In January 2025, Scottish airlineLoganair announced its Clan Loganair loyalty programme would adopt Avios as its frequent flyer currency later that year.[102] In April 2025, the British Airways Executive Club was rebranded as "The British Airways Club."[103]
