London-listed aviation stocks are driven by the Signycle Flying Hours index. IAG (owner of British Airways, Iberia and Vueling) and Rolls-Royce (engine maker) are the two purest aviation cycle plays on the LSE.
International Airlines Group (IAG) owns British Airways, Iberia, Vueling and Aer Lingus. Its premium transatlantic routes (London-New York, London-Los Angeles) are the most profitable in European aviation. IAG's business travel exposure makes it sensitive to global PMI — when corporate activity rises, business class yields surge.
The Flying Hours index at 104 is above the Signycle sell threshold of 102. Wide-body utilisation is at post-COVID highs, premium cabin pricing is at record levels, and load factors are maximised. This is historically the point to reduce airline exposure, not increase it.
IAG's fuel bill is approximately €7-8B annually. Each $10/bbl decline in Brent saves approximately €500-600M pre-hedging. Brent falling to $89/bbl from the Hormuz crisis peak provides meaningful near-term relief — but does not change the fundamental late-cycle Flying Hours signal.
The best entry for IAG historically comes when Flying Hours falls below 90 (COVID-level demand shock) or during sharp corrections to 92-96. At 104, patience is warranted. Watch for corporate travel softening as a leading indicator.
