Chicago is one of the largest transatlantic markets in the US, driven by strong corporate demand from the city’s financial, legal, and consulting sectors.

Best time to book

January, February, and November consistently offer the lowest fares, often €1,900–€3,200 round trip. All three carriers run transatlantic fare sales during these shoulder periods. Summer (June–August) and the December holiday season push fares above €5,500. Ex-US positioning through cheaper gateway cities can occasionally unlock additional savings on BA. Booking 6–10 weeks ahead is optimal for this route.

What to expect

All three carriers offer fully lie-flat beds with direct aisle access. BA’s Club Suite is the hard product leader with its privacy door and refined cabin. American’s Flagship Business is solid with a comfortable seat, though the soft product — food and service — can be inconsistent. United’s Polaris has the best pre-flight experience at O’Hare, with the Polaris Lounge offering sit-down dining, showers, and rest areas. The overnight eastbound flight (typically departing 18:00–21:00) arrives at Heathrow the following morning, making lie-flat access essential. At Heathrow, BA’s Galleries lounge serves arrivals and connections.

At the destination

London’s appeal is vast and varied. The West End theatre district, world-class museums (British Museum, National Gallery, Tate Modern), and the historic Tower of London provide a cultural foundation. Neighbourhoods like Soho, Marylebone, and Bermondsey each offer distinct dining and shopping experiences. London’s food scene has transformed in recent decades — from Indian cuisine on Brick Lane to modern British at The Ledbury and Lyle’s. The city’s parks — Hyde Park, Regent’s Park, Hampstead Heath — offer green space within the urban core. Easy rail connections reach Oxford, Bath, and the Cotswolds within 90 minutes.
