Unreal! I am about to uninstall and give up on the game altogether. Despite having spent money to acquire greenies - which I'm happy to do within reason - I'm unable to send any flights out because I need flight catering. I've purchased the flight catering facility and upgraded it to the maximum. I daily send out flight catering gifts in the hope of receiving them from friends, only to find I don't have any and need them on pretty much every flight at the level I'm on. Total joke! Unable to progress in the game unless I spend more money .... after having spent hundreds of euros to date!!! I've just about had enough!
