I would love to see a KIAH scenery. Its CO hub and there isnt anything for it. There so many airlines that fly to IAH.
Aeromexico
Air Canada
Air France
American Airlines
British Airways
Continental Airlines
Delta Air Lines
Emirates
Frontier Airlines
KLM
Lufthansa
Northwest Airlines
Qatar Airways
Singapore Airlines
TACA
United Airlines
US Airways
Practically never ending charters for Sun Country and Allegiant.
Cargolux
Saudi Cargo
China Air Cargo
Fed Ex
UPS
Air France Cargo
Cathay Pacific Cargo
Volga-Dnepr
And this isnt any corporate companies. I know you guys have to decide based off what will "sell". I am pretty sure KIAH would sell well. There is zero competition out there for this airport and there isnt any good freeware either.
Either way, keep up the good work!
