International Airlines Group S.A. (ISIN ES0177542018) opened at 435.40 pence and moved to a session high of 440.40 pence. The shares reached a low of 433.50 pence before finishing 4.20 pence below the high. Trading volume was 29,480,476 shares, while the 52-week range stood at 332.70 to 492.90 pence.

IAG's 1.87 percent advance exceeded the FTSE 100's 0.14 percent gain by 1.73 percentage points. The stock finished 56.70 pence below its 52-week high and 103.50 pence above its 52-week low. The closing level was 8 pence above the previous London close, showing a positive session after the shares opened 7.20 pence below the prior finish.

Buyback progress and analyst support shape the backdrop

IAG's capital-return programme remained a company-specific reference after the group completed EUR1 billion of its planned EUR1.5 billion buyback, as CH Aviation reported on September 23, 2026. The repurchased shares were held in treasury pending cancellation, according to the report. Bernstein maintained its Outperform rating and 550 pence target on September 24, as Aktiencheck reported.

Oil prices and bond-market concerns framed the wider London session. Shareprices said falling oil prices offset worries about bond yields as the FTSE 100 ended higher. The market backdrop was relevant for airlines because fuel costs are a major operating input, while higher yields affect rate-sensitive equity valuations.

FTSE 100 and airline peers on September 25, 2026

The FTSE 100 closed at 10,695.25, up 0.10 percent, while the FTSE 250 gained 0.40 percent to 24,261.14. easyJet closed at 675 pence, up 0.75 percent, and Wizz Air finished at 1,055 pence, up 3.03 percent. Ryanair Holdings traded at USD 55.56 in New York at 12:54 p.m. ET, up 2.82 percent, placing the airline group broadly higher during the session.

IAG's 1.87 percent gain exceeded easyJet's move by 1.12 percentage points and trailed Wizz Air's gain by 1.16 percentage points. The FTSE 100 advance provided a positive market comparison, but IAG outperformed the benchmark by 1.73 percentage points. The session therefore combined a broad London gain with stronger performance across the listed airline names.
