About the Chicago to London route
Chicago to London flies nonstop several times a day on British Airways, American and United, with fares that follow the business week more than most routes. Weekend departures and Saturday-night stays bring the price down. An agent prices the nonstops next to the one-stop options through Dublin or Iceland, which can be far cheaper in spring and autumn.
- Dublin preclearance on the way home
- A connection through Dublin on the way back lets you clear US immigration in Ireland and land in Chicago as a domestic arrival. An agent can price that routing.
- Premium economy is well served here
- All three nonstop carriers sell a premium economy cabin on this route. Worth a quote on an eight-hour overnight flight.
