Finnair A340 to JFK on November 11th

[Iberia A340-600]

Finnair will operate the A340-300 on AY5/6 on November 11, 2010 as a one-off sub for the regular A330-300. I realize this is quite a few months away but it's something to put down in the calendars.

Gordon: just a curiosity question -- given this is several month away, and it's a one-off substitution, do you have any experience as how accurate this will be eventually?

Looking at the seat maps of AY's 330 and 340, they are very similar; which excludes the possibility of swithcing equipment because of capacity reasons. I would guess that the likely cause of the switching is some kind of maintanence that require the 330 to be down by one day; and the 340 happens to be available.
