Does anyone ever operate 737-200ADVs and/or 727-200ADVs late enough in a game (2005 and 1999 respectively I believe) to have the option to retrofit winglets, and if so, do you equip them?

The current system, based purely on the exit limit, works fine for the most part. But there are… annoying discrepancies. The biggest flaw is it does not take into account how much floor space is available on the airplane.
The most annoying instance of this that I have found is that of the 747-400 and -8i. The -400 has an exit limit of 660 while the 8i has an exit limit of only 605, despite the -8i being almost 20 feet longer and typically carrying 50 more people than the -400! Another instance is the 737-800 and -900. Both have the same exit limit (189), but the -900 is about 9 feet longer than the -800 so it typically carries more people.
I think seating should be based on a theoretical maximum based on the floor space available, with an artificial cap set at the exit limit. This would allow seating arrangements to be much more accurate to real life, and most importantly, allow the 747-8i to carry way more people than it currently can in AE.

While the 767 production line is still active, the only deliveries are freighter/tanker variants. Since freight is not yet a feature in Airline Empires, I think passenger 767 production should be halted in 2014, when the last 767-300ER was delivered.

I think it would be cool if we had more worlds between the 30 and 70 year extremes we have now. The vast majority of game worlds are 30 years, one is 40 years, two are 70 years, and the sandbox and beginner worlds are only 20 years. I want to see more 40, 50, 60, and 70 year games. Maybe the people would like an 80-year 1950-2030 game?

I know the 737-900 exit limit is the same as the 737-800, but in the real world airlines are able to configure a -900 with more seats in a 2-class configuration than the -800. I don't know if there is a way to implement this in AE, but without it the -900 is just reduced to a worse -800 and we have to wait another 5 years until the -900ER comes out.
