Chicago to Barcelona Flights (ORD to BCN): Nonstops, Connections and Arrival Guide

Nonstop in summer, one stop the rest of the year

Chicago O'Hare to Barcelona has had seasonal nonstop service in recent years, with American flying the route in the warmer months. Seasonal routes are added and dropped from year to year, so check whether a nonstop is on sale for your dates before you assume it. Outside that season, and whenever the nonstop is full, you connect once, and O'Hare's long list of European flights makes that easy:

• Via Madrid with Iberia or American: Iberia flies O'Hare to Madrid, and the Madrid to Barcelona shuttle is about an hour and a quarter. American and Iberia are oneworld partners.
• Via London Heathrow with British Airways or American, with British Airways or Vueling on to Barcelona.
• Via Lisbon with TAP Air Portugal, which flies from Chicago.
• Via Dublin with Aer Lingus, with US preclearance on the way home.
• Via Frankfurt or Munich with Lufthansa, or Zurich with Swiss: United sells these as Star Alliance partners, and United itself flies to Europe from O'Hare with connections onward.
• Via Paris with Air France or Amsterdam with KLM, often with Delta.
• Via Istanbul with Turkish Airlines or via Reykjavik with Icelandair, both of which serve Chicago.

A one-stop trip typically takes 11 to 14 hours eastbound, against about nine hours on the nonstop.

Flight time and distance

The great-circle distance from ORD to BCN is about 4,400 miles (7,100 km). A nonstop takes roughly 8.5 to 9 hours eastbound with the jet stream behind it, and around 10 hours westbound into the wind. Eastbound flights leave Chicago in the late afternoon or evening and land in Barcelona the next morning or around midday. Westbound flights leave Barcelona late morning or early afternoon and land in Chicago the same afternoon or evening.

If you connect through Madrid, London or Lisbon, the second leg is short, under two and a half hours, so most of the travel time is the Atlantic crossing.

Leaving from O'Hare

O'Hare has four terminals in use. United uses Terminals 1 and 2, American uses Terminal 3 and parts of Terminal 5, and most foreign airlines, including Iberia, British Airways, Lufthansa, Swiss, Air France, KLM, TAP, Aer Lingus, Turkish and Icelandair, use Terminal 5, the international terminal. The airport transit system connects all terminals and the remote parking lots; allow time to move between Terminal 5 and the others, as they are not all connected behind security.

The CTA Blue Line runs from downtown to the station beneath Terminals 1, 2 and 3 in about 45 minutes and is the most reliable way to the airport in traffic. For an evening international flight, arrive three hours early if you are checking bags; Terminal 5 security is busiest late in the afternoon.

Arriving at El Prat and getting into Barcelona

Barcelona El Prat has two terminals. Terminal 1 handles most full-service and long-haul airlines, including American, Iberia, British Airways and Lufthansa; Terminal 2 is used mainly by low-cost carriers such as Ryanair and easyJet. A free shuttle bus links them in about 10 minutes. If you arrive on a nonstop from Chicago, or via London, Dublin or Istanbul, you go through Schengen passport control in Barcelona; arrivals via Madrid, Lisbon, Frankfurt, Paris or Amsterdam already cleared it at the connecting airport.

The airport is about 15 km southwest of the city centre:

• Aerobus: express buses from both terminals to Placa d'Espanya and Placa de Catalunya in about 35 minutes, every few minutes most of the day. The simplest option for central hotels.
• Rodalies R2 Nord train: from the station at Terminal 2 to Sants, Passeig de Gracia and Clot in about 25 to 30 minutes. From Terminal 1, take the shuttle bus to Terminal 2 first.
• Metro L9 Sud: serves both terminals and connects with other metro lines, but is slow to the centre and needs a specific airport ticket.
• Taxi: 25 to 40 minutes to the centre, metered with an airport supplement; use the official rank outside arrivals.

Pickpocketing is common on airport trains and in the metro, so keep bags in front of you.

When to fly and when to book

Barcelona's peak is June to September, when the beaches are full, cruise ships call daily and fares from Chicago are at their highest. August is the hottest month, and some local businesses close for holidays. The festival of La Merce in late September and the Mobile World Congress in late February or early March push hotel rates sharply for a few days each.

The sweet spots are April to May and October, with warm days, smaller crowds and better fares. November to March is mild by Chicago standards, rarely below 10 degrees Celsius in the day, with the lowest fares outside Christmas. Book summer three to five months ahead, especially if you want the nonstop; six to ten weeks is usually enough the rest of the year.

Entry requirements and documents

Spain is in the Schengen Area. As of recent rules, US passport holders can visit for short stays without a visa, with a passport valid for at least three months beyond the date you leave Schengen. The EU's Entry/Exit System now takes fingerprints and a facial photo from most non-EU visitors at their first Schengen border, and the ETIAS travel authorisation has been delayed more than once, so check the official EU travel pages before you fly. Other nationalities should check with the Spanish consulate.

Time zones and jet lag

Barcelona is seven hours ahead of Chicago for most of the year. Both observe daylight saving time on slightly different dates, so the gap is six hours for a few weeks in March and in late October and early November. The overnight flight is short, so you arrive tired; stay out in the daylight, and adjust to Spanish hours, with lunch after two and dinner after nine, which actually helps your body clock shift. The return, landing in Chicago in the afternoon, is easier.

What travellers on this route get wrong

The first mistake is assuming the summer nonstop runs all year and planning a spring trip around it. The second is boarding the R2 train at Terminal 1, where there is no station; you need the shuttle to Terminal 2 or the Aerobus. The third is keeping a phone in a back pocket on Las Ramblas or the metro, where pickpockets are skilled and busy.
