IFR, back as far as row 10 (10 doesn't recline as in front of exit rows). Exit rows 11/ 12 but seats seem to be Very Solid on the.. err.. derrier.
When flying GB, they often switch the a/c around and I have found that an Airbus321 turns up, even after having done an OLCI on a320 seat map. If on 321, still think it's back to row 12, but you are better off sitting in the front cabin, (row 8 or 9?) Enjoy, and GB are now doing trial CE u/grades for £50.00 if you fancy chocs and a newspaper (remember those?)^
