We highlighted the really cheap business class tickets for next summer to Europe last month.
They have been coming and going and it's amazing to see such great fares hanging around.
The current variant is valid for departure from San Jose, CA and Portland, OR or Seattle, WA to Paris (CDG).
Now it gets even better, since these flights are available as BA codeshare on American Airlines. Such flights can be booked with a $400 AARP discount (only flights from the US in Business on BA). All you need to do is sign-up for a $16 yearly membership with AARP.
You can search BA codeshares only by using the ITA Matrix with these search parameters.
The AARP discount is limited to March 31 2015. However, many of these fares are available well into summer. If you don't want to take advantage of that discount (or don't like AA business class) – the fares can be booked at Cheapoair among others.
