If you started in Dublin you may find the the cost of Business is often about half. Yes you have to get there but you could do that inexpensively enough and think of it as an adventure.

You can often fly DUB-LHR-USA-LHR for €2000 or less. I have paid €1200 for April albeit ending in Malaga where i live.

Google flights is a good place to start. Below is a starter for 10 for Jan and Feb in Business - one person showing return flights from Dublin to JFK @ €xxxx flying OneWorld. Other cities are available.





NB You won't get double teir points if you choose this routing.
