IB is using 342 code for their low J A340-300. So technically it's a 300 series but with less J and more Y seats. They often switch between the two versions of the A340-300 and even the -600 series. But don't worry, the product is really the same (old full flat), which is very comfortable and spacious - but not very lucrative for the airline due to the huge seat pitch.
