That's a great idea! I found having to manage passenger AND cargo flights at the same time really tiring in Evolution. So I just ignored the cargo LOL. I still play AT till this day... in my free mode save game I had all the routes with almost a hundred airplanes.
Talk about addicting hahaha! I also absorbed all other competitors and had 8 gates at use almost 24/7.
I did notice though that almost every animated passenger I had missed their flight because the distance from the check-in counters to the gates are too long. Gate 8 had a glitch too, passengers would just walk straight through the wall, airplane, runway, and -- err -- off the screen or walk in circles by the gate till the day ends... Thought I'd share. :p Never thought there were still people like me who appreciates AT. ^-^
