Few corrections folks!
1) On the VS LGW B744's upstairs is all Premium Economy.
2) The seats are Recaro J class seats NOT first class, sadly not as comfortable as the J2000 seats.
3) Restrictions on steering on the A346 are more due to its length (longer than a B744) and the aircraft is more use on long range routes than "holiday" destinations!
4) The good news is that it is NOT a classic so has more chance of getting you there on time!!!
