I got super duper lucky on my fare search for my upcoming RS tour to Scandinavia... found a 1$ one way fare from JFK to ARN via LHR. One dollar plus taxes of $320. Economy tiny seats, but still....wow! The fare was still on the British Air website the morning of Feb 4th. Good luck!
what date range was this good for?
And you are just now telling us about it? ;-)
(Teasing) Congratulations!
Did you just "happen" on the low cost or were you notified by BA?
What is the return flight going to cost?
I searched for information about that, at the internet website BritishAirways.com. For the Round trip : flying from New York Kennedy airport to Stockholm's ARN airport, via London Heathrow Airport, and return to New York Kennedy airport, the lowest price I saw is 761.03 U.S. Dollars. Includes tax and airport fees. That is the "E-mail quote". It is for flights on some days in February, 2015. Some of the flight departure times and flight arrival times are not bad.
It was a fluke Ron...like winning the lottery. These super low fares happen from time to time when the airline's central computer hiccups. Fortunately they always honor these crazy fares!
