Flying Chicago to London covers about 3,940 miles, linking O'Hare International Airport (ORD) with London Heathrow Airport (LHR); a nonstop takes roughly 8h25, with winds moving it either way. American Airlines, British Airways, and United Airlines all carry nonstop award space in the data. The Boeing 787-10, Boeing 767-300, and Boeing 787-9 all appear on those nonstop award segments. Only about 7% of the award options in the data are nonstop, so most results connect.
On a long-haul trip like Chicago–London, pick the cabin before the program. The economy floor is a partner booking on an American Airlines nonstop, with no connection to trade off against the points. The data doesn't include taxes on that seat, so confirm the cash portion at checkout. Measured against economy, premium economy is about 3.7 times the points and business about 5 times, though the cheapest business award carries heavy fees. The cheapest seat needs GOL Smiles miles; without a balance there, compare the bank-transfer programs before moving anything.
GOL Smiles wins economy at 9,500 points on an American Airlines nonstop. Alaska Atmos Rewards takes premium economy at 35,000 points on a British Airways nonstop. Virgin Atlantic Flying Club is cheapest in business class at 48,500 points. Alaska Atmos Rewards lists first class from 55,000 points, but the fare connects, which usually means first on one leg only; read every segment.
The Chicago–London nonstop is contested on points, with carriers from oneworld (American Airlines, British Airways) and Star Alliance (United Airlines) all showing award space. That gives partner currencies from both alliances a way onto a nonstop. When nonstop space is gone, the cheaper connecting awards in the data route through New York, Boston, and Toronto. Partner pricing sets the business-class floor: Virgin Atlantic Flying Club books Air France as a SkyTeam partner, and no program prices Air France lower in that cabin at last check.
Landing in the London area, London City (LCY) and Gatwick (LGW) both run 22,500 points in economy against the 9,500-point floor, so they're a last resort when Heathrow space is gone. Also tracked into London: Boston to London, from 6,000 points at last check. Check the arrival airport code on the award before moving points.
