As a local to this area, I was excited to check out ORBX’s Southampton and I have to say, I am thoroughly impressed.
ORBX did an incredible job on this one, it’s not the biggest of airports with the 737/A320 family being the largest aircraft supported at this airport.
From memory of previous flights to Southampton, the surrounding area feels improved as well, there is a slightly noticeable performance hit for me but that happens with a lot of addons, I would say similar performance to some of ORBX’s other UK airports (Leeds Bradford, Newcastle)
I can especially recommend this you fly turboprops, the freeware Q400 goes perfectly with this.
Here’s a few screenshots so you can see for yourself, I will post more screenshots throughout the day highlighting more of this beautiful airport.
