James I could not agree with you any more. The A343 PE seats are horrible. The A346 PE could even be sold as almost business class. But on the 343 they should be sold as well, Joke Class.
But the customer is not to blame. Flying VS is a gamble, you never really know what aircraft or seat type you will get. Welcome to IAD, flip a coin, a343 or a346, lord only knows 
[:(] I couldn't agree more! So inconsistent. I've had great flights in UC on A346 and B742 and in PE on B744 and even B742 and cr@p flights in PE on A343s. OK the B742s were a few years ago, but were much better than the A343s of more recent times. SOOO inconsistent.
PE was a great product 10 years ago (on B747s) but has been allowed to wither and die. How can VS refurbish the A343 and forget about the notorious PE cabin and seats on that plane? Apparently they had numerous complaints about them. One flight i was on, almost everybody called the CSM and complained.
Also interesting comments about VS to IAD. I've flown that route about twice a year for past ten years. 5 years or so ago it used to be a FULL B742 or B744, what happened?
