Flew through the Private Jet Terminal on Sunday - a great experience which I'd recommend unequivocally! Check in was a breeze, and virtually non existant - I handed my passport to the staff before walking through the metal detector and was immediately given my boarding pass after passing through.
Sandwiches and snacks are served in the lounge, which has great views of the apron and runway - you'll find spirits on the bar and mini bottles of Laurent Perrier in the fridge.
Around 20 minutes prior to departure you're bussed straight to the front stairs - the other stairs had already been removed, and as soon as we boarded they closed the doors and started push-back. The cabin crew had time to serve a glass of LPGS before we took off only around 5 mins later!

I would do it again and again and again!
