Award availability has opened up for United business class flights from Chicago O'Hare (ORD) to London Heathrow (LHR) on April 5, 2026. At 88,000 miles with minimal taxes, this is a solid redemption for transatlantic business class, which typically runs around 140,000 miles on this route through MileagePlus.
The low taxes make this particularly appealing. Many London-bound awards come with fuel surcharges that can add hundreds of dollars to the total cost, but this booking rings up at just $33 out of pocket. Current availability appears healthy, with plenty of seats showing for the April 5 date.
This rate works well for families looking to use miles for a spring break trip or anyone planning ahead for next year. April weather in London tends to be mild, and you'll be past the worst of the winter crowds while still ahead of peak summer pricing.
One practical note: award availability can shift quickly, so if this fits your plans, book sooner rather than later. United allows free changes and cancellations on award tickets up to 30 days before departure, giving you flexibility if plans change.
