Chicago to Kuala Lumpur Flights (ORD to KUL): Best Connections, Flight Time and Arrival Guide

One stop is the only way to fly this route

No airline flies nonstop between Chicago O'Hare and Kuala Lumpur. The distance is near the limit of what any aircraft can fly commercially, and Malaysia Airlines does not serve the United States, so every journey connects once, either in the Gulf or in East Asia. Which hub you pick decides how long the trip takes and where you spend your layover.

As of recent schedules, the Gulf carriers are the most common choice from Chicago. Qatar Airways connects through Doha, Emirates through Dubai and Etihad through Abu Dhabi, all with nonstops from O'Hare and onward flights to Kuala Lumpur. Turkish Airlines does the same through Istanbul. These routings are long but usually involve a single, well-timed connection.

The East Asian option is often faster. Cathay Pacific connects through Hong Kong, EVA Air through Taipei, Korean Air through Seoul Incheon, and Japan Airlines and ANA through Tokyo. Malaysia Airlines is a oneworld member, so an American or Japan Airlines ticket from Chicago may put you on a Malaysia Airlines aircraft for the last leg from Tokyo or Hong Kong. Check each segment's operating airline when you compare.

Total travel time and distance

The great-circle distance between ORD and KUL is roughly 9,300 miles, about 15,000 km. No single flight covers it, so what matters is total time. Westbound via East Asia, plan on 21 to 25 hours from leaving Chicago to landing in Kuala Lumpur, with the transpacific leg taking 13 to 16 hours and the Asian connection three to six hours more.

Via the Gulf, the Chicago to Doha or Dubai leg takes about 13 to 14 hours, and Doha or Dubai to Kuala Lumpur adds another seven to eight hours. With a layover, total times of 24 to 28 hours are normal. Eastbound, the return is similar in total but the transpacific leg is one to two hours shorter with the jet stream behind you.

You cross the International Date Line going west via Asia, so you arrive two calendar days after you leave. Via the Gulf you do not cross it, but the overnight flights still mean you land a day or more later.

Departing from Chicago O'Hare

O'Hare's international departures mostly leave from Terminal 5, which is where Qatar Airways, Emirates, Etihad, Turkish Airlines, Cathay Pacific, EVA Air and Korean Air check in. Japan Airlines also uses Terminal 5, while ANA and United depart from Terminal 1 and American from Terminal 3. The free Airport Transit System train links all four terminals.

Most long-haul departures to Asia and the Gulf leave in the early afternoon or late evening. Terminal 5 security can be slow when several widebodies board at once, so arrive three hours ahead for a long-haul flight with checked bags. The CTA Blue Line reaches O'Hare from downtown in 40 to 50 minutes and drops you at Terminal 2, from where you take the transit train to Terminal 5.

If you are starting in Chicago on a domestic connection, note that a change from a United flight at Terminal 1 to a Gulf carrier at Terminal 5 means leaving security and clearing it again. Allow at least two and a half hours.

Arriving at Kuala Lumpur International

KLIA has two terminals. Terminal 1 handles full-service airlines, including Malaysia Airlines, the Gulf carriers, Cathay Pacific, EVA Air, Korean Air and the Japanese carriers. Terminal 2, formerly known as klia2, is the low-cost terminal used by AirAsia. Long-haul arrivals at Terminal 1 usually land at the satellite building and take the Aerotrain or a shuttle bus to the main terminal for immigration.

Immigration for US passport holders uses the foreign visitor lanes, and autogates have been extended to many nationalities, which has cut queues considerably. From the airport into the city:

• KLIA Ekspres: a nonstop train to KL Sentral in about 28 minutes, with departures every 15 to 20 minutes through the day. It is the quickest and most predictable option.
• KLIA Transit: the same line with intermediate stops, taking about 35 to 40 minutes.
• Taxi or ride-hailing: 45 to 75 minutes to the city centre depending on traffic, from the ranks and designated pick-up zones at the arrivals level.
• Airport buses: cheaper and slower, running to KL Sentral and other points in roughly an hour.

KL Sentral connects to the KTM Komuter, LRT, MRT and monorail systems, so most hotels in the Golden Triangle or Bukit Bintang are a short onward ride.

When to fly and when to book

Kuala Lumpur is hot and humid all year, so the weather matters less than the rains. The west coast of peninsular Malaysia is wettest from September to November, and the east coast and islands are affected by the northeast monsoon from November to February. March to August is drier and better for island trips.

Fare pressure follows holidays rather than seasons. Chinese New Year, Hari Raya at the end of Ramadan, the Malaysian school holidays and the Christmas to New Year period all push up prices and fill the Asian connecting flights. The US summer also tightens seats on the Gulf and Tokyo legs. Book three to five months ahead for those periods; six to ten weeks is usually enough otherwise.

Entry requirements and documents

As of recent rules, US passport holders can enter Malaysia for short tourist stays without a visa, provided the passport is valid for at least six months. Malaysia also requires most foreign visitors to complete the Malaysia Digital Arrival Card online within the three days before arrival, and airlines may check that you have done so. Confirm the current rules on the Malaysian Immigration Department website before you fly, because arrival card and autogate eligibility have changed several times.

Bring proof of onward travel and your first night's accommodation. Malaysia is strict on drugs and on some medications, so carry prescriptions in their original packaging with a doctor's letter.

Time zones and jet lag

Kuala Lumpur is 13 hours ahead of Chicago during US daylight saving time and 14 hours ahead in the US winter. Malaysia does not change its clocks. The gap is close to a full half-day, so your body clock arrives almost exactly inverted, and it tends to take four or five days to settle whichever direction you fly.

Via Asia, you typically land in Kuala Lumpur late at night or in the early morning; via the Gulf, arrivals cluster in the afternoon and evening. An afternoon arrival is the easier one, because you can stay up until local bedtime. Get outdoors in daylight the next morning and avoid long naps.

What travellers on this route get wrong

The first mistake is comparing fares without comparing total time, then discovering that a cheaper routing adds a seven-hour layover. The second is skipping the Malaysia Digital Arrival Card until the queue at immigration. The third is landing at Terminal 1 and following signs for Terminal 2 because a friend mentioned klia2; the terminals are separate buildings linked by train and bus. Each costs an hour or more at the end of a very long day.
