D and F, I don't know. I only heard the rumour towards the end of last year.
But like I said who knows how airlines are going to react to the current situation so it might be worth keeping your hat in the freezer for a few years!
The 737 and A320 family are very common, for good reason, and have obviously proven to be reliable and efficient over the last couple of decades. But, how profitable are they going to be when oil hits $200 per barrel and the number of people using air travel declines? It's going to be easier to fill, and less expensive to operate, a smaller aircraft particularly on UK short haul and near European routes. Flybe have already proved this with the Q400 and, to quote the Chief Commercial Officer on a recent press release "Flybe is in rude financial health". Can't say the same for Easy now can we.
