Several airlines offer non-stop flights between London and New York City. Here are some prominent airlines that operate non-stop flights on this route:

1. British Airways
2. Virgin Atlantic
3. Delta Air Lines
4. American Airlines
5. United Airlines
6. Norwegian Air Shuttle (Note: As of my knowledge cutoff in September 2021, Norwegian Air Shuttle had temporarily suspended its operations. It’s advisable to check their current status before making any travel plans.)

These airlines typically operate regular non-stop flights between major airports in London, such as London Heathrow (LHR) and London Gatwick (LGW), and airports in New York City, primarily John F. Kennedy International Airport (JFK) and Newark Liberty International Airport (EWR).

It’s important to note that airline schedules and routes can change over time, so it’s recommended to verify the availability of non-stop flights and check with the respective airlines or online travel agencies for the most up-to-date information regarding flight options, timings, and any potential changes in services.
