Chicago O' Hare International Airport is located to the northwest of the center of Chicago and is a good option for those coming from the north side of the city and are traveling on cheap flights from Chicago to London. Chicago Midway Airport is located southwest of the city and makes a good choice for those that are coming from the south side of the city.

When traveling internationally from Chicago to London, you will find that there is quite a bit more choice in terms of flights to London Heathrow Airport as opposed to London City Airport. That said, if you are going to be staying somewhere on the east side of London or anywhere east of the city of London, the London City Airport is going to be far more convenient because London Heathrow Airport is west of London and the trip from this airport to the east side of London can be quite lengthy.
