Any particular OTA you're using? Google Flights prices those days as $456. I see $429 on a lot of other dates, but no $351.

I found 358 euro in September 2015 using ITA Matrix but on AF. BA showing as 807 euro.

Priced it easily using multicity on ba.com at EUR 309.31. Seems to be bookable.

Lots of other variations possible. Like this one returning from SFO @ ~EUR 340:

Is this for these specific dates only? I would love to do this trip in August sometime.

$80+ through EOS. Sunday stay. 3 month max.

Luxembourg to Montreal / Chicago to Berlin for $246 here

Seems Mr johnspat and his famous blog his back...
That was a long time :-))))

Yeah, and I love how they put the words ERROR FARE!! to generate traffic even though it's not an error fare.. :td:

What's EOS?

End of Schedule

How do I translate flugladen.de? I can't figure out how to do multicity?

Try it with "Stopover" ;-)

Tried it, it needs 3 flights and dates

Thanks! I just booked this. Can someone explain to me how this is not a fare error? Surely BA didn't decide they wanted to offer a 110 euro transatlantic flight?
Also, how long should I wait before safely booking hotels and such? Is there a chance of the airline canceling my tickets?
