Ordering aircraft is a strategic part of the game. It would be nice to get a news article about Boeing looking to increase production of the 727 line or that Douglas is decreasing production of the DC6 due to lower order back log, etc. Knowing a line might increase or just did might push an airline to order more frames. This is realistic to the real world as well. I had a time where I placed an order a couple days early before a line expanded and I could have gotten earlier slots. I feel manufactures would communicate these things more.
