It doesn't really matter which type they chose, although you can shoot holes in a Boeing and it will still fly, but by the time all these a/c arrive and the business has picked up, who is going to be around to fly them???? That was the question before OBL. and will remain the question over the next few years. And, if charter airlines, the originators of cost conscious operations, chose Boeings, I'd be inclined to go with their choice.
Remember though, there is more to life than strapping an aluminium tube to your arse for 10 hours a day.
