It’s been a while since we last had an update from Oliver Pabst regarding his Airport Enhancement Services (AES) package. Apparently he has been far from idle, however, and the release notes for version 2.35 details some of the reasons for this.
In addition to the usual new releases, of which there are several, the release notes (which can be found here), discuss some of the work that has been put into making the package more flexible, with visible passengers, left-side cargo loading and more potentially being added in the future.
The full list if airports now supported and their cost in credits can be found here, while the download for the new version can be found on the product page at simMarket, where you can also purchase more credits if you need them.
