737s have already flown transatlantic flights; SAS used to run the oil-company special, a direct service, all business-class, on a 737 from Stavanger (Norway) to Houston (United States).

Similarly, British Airways still flies between London City airport and New York/JFK on an Airbus A318, also all business-class.

(and though the headline only mentions the 737, the article correctly points out that Airbus is aiming for this market too, with a planned long-range version of the A321neo)

WestJet fly from Glasgow to Toronto, with a stopover in Halifax, with a 737-700 as of last year. Unlike those examples, this has no true business class seating at all.

But the A318 can only do the return flight non-stop, they stop to refuel in Shannon on their way to JFK. Mostly due to the short runway in London City, but still not really a comparison to what low cost carriers are planning.
